CAT Practice Test - 8 - Question 1

DIRECTIONS for the question: Read the passage and answer the question based on it.

The stylization underlying all existing writing systems is at the root of orthography, which literally means "drawing right" As long as writing was based on drawing a recognizable picture, its exact shape could vary. Once written symbols became a matter of convention, there was only a single way to spell them properly, or a single "orthography".

A second factor that drew writing away from pictography was the problem of drawing pictures of abstract ideas. No picture could possibly depict freedom, master and slave, victory, or god. Frequently, an association of ideas did the trick. In cuneiform writing, a divinity was a star; the profile of a face with the mouth touching a bowl meant a ration of food. Unfortunately, clever as they were, these conventions only meant anything to the trained eye --the direct connection from picture to meaning was lost.

Another trick consisted of exploiting the similarity between certain sounds to draw what were essentially visual puns. This is known by historians as the rebus principle. It involves the use of a pictogram to represent a syllabic sound. This procedure converts pictograms into phonograms. This kind of transcription of meaning progressively gave way to writing sounds. With the rebus principle, the Sumerians and the Egyptians gradually created an array of symbols that could transcribe any speech sound in their languages.

The Egyptians and the Sumerians thus came very close to the alphabetic principle, but neither managed to extract this gem from their overblown writing systems. The rebus strategy would have allowed them to write a word or sentence with a compact set of phonetic signs, but they continued to sup­plement them with a vast array of pictograms. This unfortunate mixture of two systems, one primarily based on sound, the other on meaning, created considerable ambiguity.

With the wisdom of hindsight, it is clear that the scribes could have simplified their system vastly by choosing to stick to speech sounds alone. Unfortunately, cultural evolution suffers from inertia and does not make rational decisions. Consequently, both the Egyptians and the Sumerians simply followed the natural slope of increasing complexity. Cuneiform notation added "determinative" ideograms to clarify the concept of the accompanying signs. Each marked the semantic categories of words: city, man, stone, wood, God, and so on. For instance, the character for "plow:' accompanied by the deter­minative "wood;' meant the agricultural tool. Determinatives also helped specify the meanings of words written in syllabic notation -a useful trick since any given syllable often corresponded to several homophone words (much like "one" and "won").

Why do mixed writing systems appear to constitute such a stable attractor for societies throughout the world? The reason for this probably lies at the crossroads of multiple constraints: the way our memory is structured, how language is organized, and the availability of certain brain connections. Our memory is poorly equipped for purely pic­tographic or logographic script, where each word has its own symbol. The mere notation of sounds would be equally unsatisfactory. Reading would be comparable to decoding a rebus-it wood bee two in knee fish hunt. A mixed system using fragments of both sound and meaning appears to be the best solution.

Q. In the fifth paragraph, the word ‘determinative' can be replaced by

Detailed Solution for CAT Practice Test - 8 - Question 1

The passage states that determinative ideograms helped to clarify the concept of the accompanying signs, which means that the ideograms described the accompanying signs or gave some additional information of the signs or assisted in understanding the meaning.

► Option1 - Determined means resolute or solved or decided which cannot fit in the context.
►Option 3 - Portentous means ominously significant - there is nothing threatening that is talked about in the passage.
►Option 4 - Influential means domination or importance which also doesn't fit the meaning.

Q. What is the purpose of using this line in the passage - it wood bee two in knee fish hunt.'?

Detailed Solution for CAT Practice Test - 8 - Question 2

The Rebus principle is where sound of words is used to write in any language. The sentence also shows that if words are written simply according to sounds, the sentence can be completely different from what one wants to convey.

►Option 1 - The example is of homophones and not homographs - a word of the same written form as another but of different meaning and usually origin, whether pronounced the same way or not, as bear - "to carry; support" and bear - "animal" or lead - "to conduct" and lead - "metal."
►Option 2 - The sentence should correctly read - It would be too inefficient. The sentence is supposed to explain how writing words using sounds can create nonsensical sentences.
►Option 4 -  Unequivocalness means clarity. What the sentence shows is actually equivocalness or ambiguity.

Q. From its inception in Mesopotamia, the "virus" of writing spread quickly to the surrounding cultures. The epidemic, however, remained confined, in all societies, to a small group of specialists. The complexity of this invention curbed its capacity to spread. Even in present-day China, scholars must learn several thousand signs. As recently as the 1950s, the rate of illiteracy in the adult Chinese population was close to 80 percent-before _________ and massive investment in education brought this figure down to about 10 percent.

Detailed Solution for CAT Practice Test - 8 - Question 3

The paragraph given is of course related to the passage given. The Chinese language has several thousand signs which one has to learn. Obviously the illiteracy rate would be high as our memory is poorly equipped for purely pictographic script. Hence simplification of writing would be able to get down the rate from 80 percent to 10 percent.

►Option 1 - Cultural evolution is not going to help in remembering several thousand signs.
►Option 3 – Literacy is more about the written language – a dialect is usually a spoken language – so it would not have too much of impact on literacy.
►Option 4 - Making learning mandatory without looking into the fact that several thousand signs are to be memorized and that too by adult population will not bring the rate down to 10%.

CAT Practice Test - 8 - Question 4

DIRECTIONS for the question: Read the passage and answer the question based on it.

Why should we be concerned with symmetry? In the first place, symmetry is fascinating to the human mind, and everyone likes objects or patterns that are in some way symmetrical. It is an interesting fact that nature often exhibits certain kinds of symmetry in the objects we find in the world around us. Perhaps the most symmetrical object imaginable is a sphere, and nature is full of spheres—stars, planets, water droplets in clouds. The crystals found in rocks exhibit many different kinds of symmetry, the study of which tells us some important things about the structure of solids.

But our main concern here is not with the fact that the objects of nature are often symmetrical. Rather, we wish to examine some of the even more remarkable symmetries of the universe—the symmetries that exist in the basic laws themselves which govern the operation of the physical world.

First, what is symmetry? How can a physical law be “symmetrical”? The problem of defining symmetry is an interesting one and we have already noted that Weyl gave a good definition, the substance of which is that a thing is symmetrical if there is something we can do to it so that after we have done it, it looks the same as it did before. For example, a symmetrical vase is of such a kind that if we reflect or turn it, it will look the same as it did before. The question we wish to consider here is what we can do to physical phenomena, or to a physical situation in an experiment, and yet leave the result the same.

The first thing we might try to do, for example, is to translate the phenomenon in space. If we do an experiment in a certain region, and then build another apparatus at another place in space (or move the original one over) then, whatever went on in one apparatus, in a certain order in time, will occur in the same way if we have arranged the same condition, with all due attention to the restrictions that we mentioned before: that all of those features of the environment which make it not behave the same way have also been moved over.

In the same way, we also believe today that displacement in time will have no effect on physical laws. Another thing that we discussed in considerable detail was rotation in space: if we turn an apparatus at an angle it works just as well, provided we turn everything else that is relevant along with it. On a more advanced level we had another symmetry—the symmetry under uniform velocity in a straight line. That is to say—a rather remarkable effect—that if we have a piece of apparatus working a certain way and then take the same apparatus and put it in a car, and move the whole car, plus all the relevant surroundings, at a uniform velocity in a straight line, then so far as the phenomena inside the car are concerned there is no difference: all the laws of physics appear the same. 
Excerpted from the Feynman Lecture on Physics, Vol I

Q. You would ask the author all the questions given below, except,

Detailed Solution for CAT Practice Test - 8 - Question 4

The answer to this is given in the example of the moving car and the apparatus mentioned at the end of the passage.

We have been discussing that symmetry in space is not affected by displacement in time hence we would want to know whether a change in scale makes a difference – which is what both 1 and 2 are asking.

We would also be interested in knowing if any other symmetry exists.

Q. What can you say about the laws of physics with reference to the passage?

Detailed Solution for CAT Practice Test - 8 - Question 5

The only thing we can say is that displacement of time does not affect the physical laws.

The other three options are incorrect, because the first option is vague as it is not certain it is talking with reference to symmetry, the third option is incorrect – refer to if we have a piece of apparatus ............ no difference: all the laws of physics appear the same and option 4 is incorrect because it is not mentioned in the passage that in all types of symmetry the laws are adhered to.

Q. What is the tone of the passage?

Detailed Solution for CAT Practice Test - 8 - Question 6

Analytical writing is simple, direct, concise, and to-the-point and which means looking at something in a logical manner, which is exactly how the passage has been written.

Option A – A critical tone would mean a fault finding tone, which the author is not using.
Option B – The author makes no harsh, taunting or cutting remarks. Hence the tone cannot be sardonic.
Option D – The author does not express any doubt, or skepticism, about anything he is saying, hence we can rule out this option.

CAT Practice Test - 8 - Question 7

DIRECTIONS for the question: Read the passage and answer the question based on it.

Workhouses have long assumed a central place in studies on the poor laws. While we know that the majority of relief claimants were actually given outdoor relief in money or in kind from the parish pay-table, welfare historians have shown that many individuals entered workhouses during moments of both short and long-term need. This dynamic has a long history. The Elizabethan poor laws permitted parishes to find accommodation for ‘poor impotent people’ in addition to the requirement to ‘set to work’ their poor. Some cities had obtained their own ‘Local Acts’ which contained specific legislation designed for the specific welfare needs of that locale. Central to these Acts was the workhouse. The first Local Act was passed in 1696 for the Civic Incorporation of Bristol.

Born in Staffordshire, Gilbert was a chief land agent to Lord Gower and a keen poor law reformer. Through his work, he developed an immense political, legal, commercial and industrial knowledge which enabled the Gower estate to become one of the most prosperous in England. Gilbert’s concern for the poor may have stemmed out of his role as agent, which had allowed him to take onboard the role of paymaster for a charity of naval officers’ widows. As Marshall noted, Gilbert thought old parish workhouses were ‘dens of horror’.  Such workhouses were too uncomfortable for those who were in poverty due to no fault of their own and places where the young were susceptible to ‘Habits of Virtue and Vice’ learnt from ‘bad characters’. For the sake of both the poor and the rates, Gilbert thought that workhouses should be reformed to promote industrious behavior.

These ideas culminated in a new bill and the subsequent Act of 1782 which enabled parishes to provide a workhouse solely for the accommodation of the vulnerable.  Although such residents were, as Gilbert put it, ‘not able to maintain themselves by their Labor’ outside of the workhouse they were still to ‘be employed in doing as much Work as they can’ within the workhouse.  Work was therefore a part of everyday life within a Gilbert’s Act workhouse. The able-bodied were only to be offered temporary shelter and instead were to be found employment and provided with outdoor relief. Those who refused such work (the ‘idle’) were to endure ‘hard Labor in the Houses of Correction’.

How was such a workhouse to be established and managed? Gilbert wanted to allow parishes to unite together so that they could combine their resources and provide a well built and maintained workhouse. According to Steve King, Gilbert’s Act was the first real breach of the Old Poor Law principle ‘local problem - local treatment’.  Yet, any ‘Parish, Town, or Township’ was also permitted to implement the law alone, and hence concerns over poverty did not always transcend parish boundaries. Gilbert’s Act workhouses were to be managed in a different way compared to the older parish workhouses. Gilbert believed that the poor laws had been ‘unhappily’ executed ‘through the misconduct of overseers’. Such officers, he claimed ‘gratify themselves and their Favorites, and to neglect the more deserving Objects’. This dim view of overseers was shared by many others at the time.

Q. What question would you like to ask the author after reading the passage?

Detailed Solution for CAT Practice Test - 8 - Question 7

Regarding these types of questions one should consider that issues/facts already mentioned in the passage do not entitle to be asked as questions.

Refer to last lines of second paragraph” Such workhouses were too uncomfortable for those who were in poverty due to no fault of their own and places ……….” Hence option D is ruled out.

Also in the second passage line “Gilbert’s concern for the poor may have stemmed out of his role as agent. …..” makes option A invalid.  

As no one was as concerned as Gilbert that’s why the Act was named after him, so no such amendments were made hence Option B is wrong.

The Obvious questions that stems is what provisions were made under the act to better the plight of workhouses/Parishes

Q. What does the term ‘poor impotent people’ imply contextually?

Detailed Solution for CAT Practice Test - 8 - Question 8

‘Impotent’ as used contextually does not signify incapability to procreate.

Hence, option A, B & D are not relevant contextually rather impotency herein implies incapacity to sustain due to lack of work/money.

Q. Which among the following is not true as per the passage?

Detailed Solution for CAT Practice Test - 8 - Question 9

Option A is clearly mentioned in the opening lines of second paragraph.

Nepotism means favoritism as the aversion for such attitude by Gilbert is mentioned in the concluding lines of the passage hence option B is ruled out.

Option C is mentioned in the last lines of second & Third paragraph - “Gilbert thought that workhouses should be reformed to promote industrious behavior.” & “Those who refused such work (the ‘idle’) were to endure ‘hard Labor in the Houses of Correction’.”

Sixteenth century will mean era from 1501 to 1599 and the first Local Act was passed in 1696 which implies late seventeenth century. As per the question Option D is the correct answer.

Consider these recent headlines: “Want to be Happier? Be More Grateful,”  “The Formula for Happiness: Gratitude Plays a Part,” “Teaching Gratitude, Bringing Happiness to Children,” and my personal favorite “Key to Happiness is Gratitude, and Men May be Locked Out.”

Buoyed by research findings from the field of positive psychology, the happiness industry is alive and flourishing in America. Each of these headlines includes the explicit assumption that gratitude should be part of any 12-step, 30-day, or 10-key program to develop happiness. But how does this bear on the question toward which this essay is directed? Is gratitude queen of the virtues? In modern times gratitude has become untethered from its moral moorings and collectively, we are worse off because of this. When the Roman philosopher Cicero stated that gratitude was the queen of the virtues, he most assuredly did not mean that gratitude was merely a stepping-stone toward personal happiness. Gratitude is a morally complex disposition, and reducing this virtue to a technique or strategy to improve one’s mood is to do it an injustice.

Even restricting gratitude to an inner feeling is insufficient. In the history of ideas, gratitude is considered an action (returning a favor) that is not only virtuous in and of itself, but valuable to society. To reciprocate is the right thing to do. “There is no duty more indispensable that that of returning a kindness” wrote Cicero in a book whose title translates “On Duties.” Cicero’s contemporary, Seneca, maintained that “He who receives a benefit with gratitude repays the first installment on his debt.”  Neither believed that the emotion felt in a person returning a favor was particularly crucial. Conversely, across time, ingratitude has been treated as a serious vice, a greater vice than gratitude is a virtue. Ingratitude is the “essence of vileness,” wrote the great German philosopher Immanuel Kant while David Hume opined that ingratitude is “the most horrible and unnatural crime that a person is capable of committing.”

Gratitude does matter for happiness. As someone who for the past decade has contributed to the scientific literature on gratitude and well-being, I would certainly grant that.  The tools and techniques of modern science have been brought to bear on understanding the nature of gratitude and why it is important for human flourishing more generally. From childhood to old age, accumulating evidence documents the wide array of psychological, physical, and relational benefits associated with gratitude.  Yet I have come to the realization that by taking a “gratitude lite” approach we have cheapened gratitude. Gratitude is important not only because it helps people feel good, but also because it inspires them to do good. Gratitude heals, energizes, and transforms lives in a myriad of ways consistent with the notion that virtue is both its own reward and produces other rewards.

To give a flavor of these research findings, dispositional gratitude has been found to be positively associated qualities such as empathy, forgiveness, and the willingness to help others.  For example, people who rated themselves as having a grateful disposition perceived themselves as having more prosocial characteristics, expressed by their empathetic behavior, and emotional support for friends within the last month.  When people report feeling grateful, thankful, and appreciative in studies of daily experience, they also feel more loving, forgiving, joyful, and enthusiastic. Notably, the family, friends, partners and others that surround them consistently report that people who practice gratitude are viewed as more helpful, more outgoing, more optimistic, and more trustworthy. On a larger level, gratitude is the adhesive that binds members of society together. Gratitude is the “moral memory of mankind” wrote noted sociologist Georg Simmel.

Q. With reference to the passage, what does the author mean by a ‘gratitude-lite’ approach?

Detailed Solution for CAT Practice Test - 8 - Question 10

First, let us look at the meaning of lite. It denotes a low-fat or low-sugar version of a manufactured food or drink product. When coupled with a soft-drink, it would mean a low-fat or calorie version of the soft drink, that is something that does not have its full impact.

When used with gratitude, it would refer to a version of gratitude that does not have the full impact or force and is a watered down version of the same.

The clue to the correct answer also lies in the following line: Yet I have come to the realization that by taking a “gratitude lite” approach we have cheapened gratitude.

Q. The author of the passage will agree with the statement:

Detailed Solution for CAT Practice Test - 8 - Question 11

This is a question which is based on the overall idea of the passage. The author of the passage clearly states the social approach to gratitude is required. But he does not state the personal approach is not needed. He, in fact, quotes that both are required.

Refer to the lines: Gratitude does matter for happiness. As someone who for the past decade has contributed to the scientific literature on gratitude and well-being, I would certainly grant that. 
In these lines, the author does accept the contribution of gratitude towards personal happiness.

Also, right through the passage, he emphasis the need of keeping the society in mind while thinking of gratitude. This makes option 3 the apt answer in this case.

Q. As per the context of the passage, identify the correct statements:

I. According to the author, the happiness industry has over-used the concept of gratitude for its own benefit.
II. According to Cicero, gratitude induces a feeling of debt in the benefactor.
III. The rewards obtained from gratitude cannot be limited to one sphere of human life.

Detailed Solution for CAT Practice Test - 8 - Question 12

Statement I can be directly derived from the lines: Buoyed by research findings from the field of positive psychology, the happiness industry is alive and flourishing in America. Each of these headlines includes the explicit assumption that gratitude should be part of any 12-step, 30-day, or 10-key program to develop happiness.

Statement II can be negated from the lines: Cicero’s contemporary, Seneca, maintained that “He who receives a benefit with gratitude repays the first installment on his debt.” 

The line actually means that if someone recieves a benefit with a feeling of gratitude, he has partially paid his debt already. The given statement states the opposite.

Statement III can be derived from the lines: Gratitude heals, energizes, and transforms lives in a myriad of ways consistent with the notion that virtue is both its own reward and produces other rewards.

CAT Practice Test - 8 - Question 13

DIRECTIONS for the question: Read the passage and answer the question based on it.

When you visit your doctor you enter a world of queues and disjointed processes. Why? Because your doctor and health care planner think about health care from the standpoint of organization charts, functional expertise, and "efficiency." Each of the centers of expertise in the health care system —the specialist physician, the single-purpose diagnostic tool, the centralized laboratory—is extremely expensive. Therefore, efficiency demands that it be completely utilized.

To get full utilization, it's necessary to route you around from specialist to machine to laboratory and to over schedule the specialists, machines, and labs to make sure they are always fully occupied. Elaborate computerized information systems are needed to make sure you find your place in the right line and to get your records from central storage to the point of diagnosis or treatment.

How would things work if the medical system embraced lean thinking? First, the patient would be placed in the foreground, with time and comfort included as key performance measures of the system. These can only be addressed by flowing the patient through the system.

Next, the medical system would rethink its departmental structure and reorganize much of its expertise into multi skilled teams. The idea would be very simple: When the patient enters the system, via a multi skilled, co-located team, she or he receives steady attention and treatment until the problem is solved.

To do this, the skills of nurses and doctors would need to be broadened so that a smaller team of more broadly skilled people can solve most patient problems. At the same time, the tools of medicine—machines, labs, and record-keeping units—would need to be rethought and "right-sized" so that they are smaller, more flexible, and faster, with a full complement of tools dedicated to every treatment team.

Finally, the "patient" would need to be actively involved in the process and up-skilled—made a member of the team—so that many problems can be solved through prevention or addressed from home without need to physically visit the medical team, and so that visits can be better predicted. Over time, it will surely be possible to transfer some of the equipment to the home as well, through teleconferencing, remote sensing, and even a home laboratory, the same way most of us now have a complete complement of office equipment in our home offices.

What would happen if lean thinking was introduced as a fundamental principle of health care? The time and steps needed to solve a problem should fall dramatically. The quality of care should improve because less information would be lost in handoffs to the next specialist, fewer mistakes would be made, less elaborate information tracking and scheduling systems would be needed, and less backtracking and rework would be required. The cost of each "cure" and of the total system could fall substantially.

Q. What is the skill enhancement required in healthcare professionals in order to make the transition to lean?

Detailed Solution for CAT Practice Test - 8 - Question 13

To do this, the skills of nurses and doctors would need to be broadened (in contrast to the narrow deepening of skills encouraged by the current system) so that a smaller team of more broadly skilled people can solve most patient problems.

►Option 1 – goes against the theme of generalisation.
►Option 3 – the passage indicates that most hospitals already have adequate IT systems.
►Option 4 – If mere training programs were solutions to our problems, we would all be living in heaven.

DIRECTIONS for the question: Read the passage and answer the question based on it.

Last semester I tried to create a college classroom that was a technological desert. I wanted the space to be a respite from the demands and distractions of smartphones, tablets, and computers. So I banned the use of technology " because asking students to be professional digital citizens had not worked.

Simply requesting that students put away their phones was an exercise in futility. Adding a line in the syllabus that there would be grade penalties for unprofessional use of technology brought about no change in their habits of swiping and clicking. They meant no disrespect. Technology pulled at them " and pulls at us " creating a sense of urgency that few can ignore. I get it. This is not a college-student problem (I've been to faculty meetings). It's a human problem.

Detailed Solution for CAT Practice Test - 8 - Question 17

Option 1 is too extreme in nature and the extreme negative sentiment expressed by it is not expressed in the paragraph.

 Option 2 is the apt answer in this case. It reflects the general tone and tenor of the author of the passage and highlights the most essential aspect of the paragraph: the problem in the classroom is one that the whole society faces right now.

► Option 3 reverses the causation in this case. The problem is one that society suffers from and classrooms are not explicitly targeted.

► Option 4 presents incorrect information. The author at no point quotes that education has been disrupted.

DIRECTIONS for the question:
The five sentences (labelled 1,2,3,4, and 5) given in this question, when properly sequenced, form a coherent paragraph. Decide on the proper order for the sentence and key in this sequence of five numbers as your answer.

1.  The Trump administration’s health-care reform bill now in the Senate, and the version that passed the House this May, will force some women to pay more again.
2.  Specifically, American women of child-bearing age paid somewhere between 52% and 69% more in out-of-pocket healthcare costs than men.
3.  Despite the incontrovertible fact that men are biologically just as responsible as women for a pregnancy happening, before the Affordable Care Act passed in 2010, women in the US paid more for health care and insurance because they are the ones who can get pregnant.
4.  Specifically, it strips out hundreds of billions of dollars from Medicaid, the insurance for the poor, which now covers over 50% of all births in many US states, and allows states to opt out of covering “essential” healthcare that includes maternity and newborn care.
5. The Senate bill was crafted behind closed doors, by 13 men and no women. A search of the language used in the 142-page draft document shows that womanhood and motherhood are, quite literally, also omitted from most of the bill itself.


Detailed Solution for CAT Practice Test - 8 - Question 18

Statements 3 &2 form a mandatory pair as 3 talks about women and men being equally responsible for pregnancy but women end up paying more. The exact numbers are being mentioned in 5. Also, statement 1,4& 5 (not in that order) talk about Trump’s administrations health care bill. ‘It’in statement 4 talks about the bill mentioned in statement 1.

1. To cope with its chronic water shortages, India employs electric groundwater pumps, diesel-powered water tankers and coal-fed power plants. If the country increasingly relies on these energy-intensive short-term fixes, the whole planet's climate will bear the consequences.
2. What India does with its water will be a test of whether that combination is possible.
3. If a country fails to keep up with the water needs of its growing cities, those cities will be unable to sustain the robust economic growth that has become a magnet for global investment.
4. Without sensible water policies, political agitation — like the recent controversies over Coca-Cola's use of groundwater in rural communities in southern and western India — will become more frequent and river-sharing negotiations with India's neighbors Pakistan and Bangladesh more tense.
5. India is under enormous pressure to develop its economic potential while also protecting its environment — something few, if any, countries have accomplished.


Detailed Solution for CAT Practice Test - 8 - Question 21

Two sentences can mark the opening of the paragraph. Sentence 3 and sentence 5.

Now, the best way to handle this question is to make pairs and then arrange them together.  

Look at the key words in sentence 3 ‘economic growth + magnet + global investment’ and ‘sensible+ policies+ Coca- Cola’ in sentence 4. Since these two sentences are sharing the same line of thoughts, 34 becomes a pair.

Sentence 1 talks about, ''what we are trying to overcome water shortage i.e. ‘planet’s climate+ consequences’ and this will put huge pressure on the evironment.

Sentence 5 talks about ‘while+ protecting environment’ i.e. the effect of cause shown in sentence 1.‘That combination’ in 2 is used for the task of developing economic potential and protecting environment. Thus 152 is a trio.

Well this makes the task easy as 5 can’t mark the opening of the paragraph ,therefore 3 will begin the paragraph . And the answer will be 34152.

Uber fits neatly into the mythology of the tech industry, which portrays itself as surfing one of the waves of "creative destruction" through which capitalism periodically renews itself. In this narrative, industrial progress involves a good deal of destruction in order to make way for new, creative, wealth-creating industries. The abolition of old timers such as licensed taxi cabs, travel agents and bookshops etc is merely the collateral damage of an essentially benign process " regrettable but necessary casualties of innovation. You don't have to be much of a sceptic to spot that this is self-serving cant. Far from being a radical innovation, Uber is a classic example of something as old as the internet itself, namely our old friend 'disintermediation'. The idea is to find a business in which the need of buyers to find sellers (and vice versa) has traditionally been handled by an intermediary, and then use networking technology to eliminate said middle man. It happened a very long time ago to travel agents and bookshops. Now it's happening to taxi firms. If this is technological innovation, then it's a pretty low-IQ manifestation of it.

Detailed Solution for CAT Practice Test - 8 - Question 22

Option 4 is the best answer.

 Option 1 is incorrect, as Uber brings something to the table, though not to the degree it claims.

► Option 2 is a close option but commits the mistake of highlighting ''economics'' instead of ''businesses''. Business models are being discussed in the paragraph, and not economics.

► Option 3 is incorrect as ''no periodic cycles'' have been mentioned in the given paragraph.

► Option 4 is the perfect representation for the paragraph as it essentially points out the significant points of the paragraph.

CAT Practice Test - 8 - Question 23

DIRECTIONS for the question: Identify the most appropriate summary for the paragraph.

The advent of cooking enabled humans to eat more kinds of food, to devote less time to eating, and to make do with smaller teeth and shorter intestines. Some scholars believe there is a direct link between the advent of cooking, the shortening of the human intestinal track, and the growth of the human brain. Since long intestines and large brains are both massive energy consumers, it’s hard to have both.

Detailed Solution for CAT Practice Test - 8 - Question 23

The message is that we could afford to have larger brains – and feed them with more energy, because the stomach and digestive system did not need too much, post our diet being converted to cooked food. Option 2 captures this idea quite well.

► Option 1 – what is stated is actually the reverse – cooking led to intellect.

► Option 3 – it actually gave many more choices than just these two.

► Option 4 – what the driver of evolution is, is a moot point. The passage does not throw too much light on this.

CAT Practice Test - 8 - Question 24

DIRECTIONS for the question:
The five sentences (labelled 1,2,3,4, and 5) given in this question, when properly sequenced, form a coherent paragraph. Decide on the proper order for the sentence and key in this sequence of five numbers as your answer.

1. The first people any rational society locks up are the most dangerous criminals, such as murderers and rapists.
2. The more people a country imprisons, the less dangerous each additional prisoner is likely to be.
3. At some point, the costs of incarceration start to outweigh the benefits: Prisons are expensive—cells must be built, guards hired, prisoners fed. The inmate, while confined, is unlikely to work, support his family or pay tax.
4. Money spent on prisons cannot be spent on other things that might reduce crime more, such as hiring extra police or improving pre-school in rough neighborhoods.
5. And—crucially—locking up minor offenders can make them more dangerous, since they learn felonious habits from the hard cases they meet inside.


Detailed Solution for CAT Practice Test - 8 - Question 24

The passage talks about imprisoning dangerous criminals and how it is beneficial to the country. However, sometimes the costs of imprisonment outweigh the benefits – money could have been spent on reduction of crime. Also when minor offenders and hardened criminals are put together, they become more dangerous.

Statement 4 and 3 both are possible answers – though more about what they do not want, than what they want.

Statement 2 is a misfit because it talks about past growth rather than current needs of its shareholders.

CAT Practice Test - 8 - Question 26

Direction: Read the passage and answer the question that follows.
Adolescence is a period of rapid growth and development bridging childhood and adulthood. Practicing healthy eating behavior is one of the most important factors to meet the nutritional needs of adolescents. Proper eating behaviors that are learned in early life are maintained in adulthood thus reducing the risk of major chronic disease. Physical and psychological changes occurring during this period usually significantly influence their dietary behaviors. As teens become more independent, they make more of their own food choices. However, being influenced by a massive amount of factors (biological, social, physical, economic, psychological beliefs, and knowledge about food) and changing of lifestyle may affect their dietary choices and eating behavior, thus making them fail to adhere to healthy eating practices. Peer pressure in colleges leads adolescents to eat non-nutritional foods like pizzas and burgers. Due to irregular college schedules, intake of caffeinated drinks increases and water intake reduces. Poor nutrition can lead to reduced concentration in studies, low stamina, depression, or poor posture.

What is the meaning of dietary behavior?

Detailed Solution for CAT Practice Test - 8 - Question 26

The word 'dietary' is an adjective form of the noun 'diet'. A 'diet' refers to the kinds of foods that a person eats routinely or habitually.
'Behaviour' would refer to the way a person acts.
Thus, the terms 'dietary behaviour' would refer to the way a person acts when it comes to eating different foods as part of their routine.
'Making choices' and 'knowledge of different types of diets'  would refer to thinking patterns, and 'behaviour' refers to actions and not thinking. 
'Drinking caffeinated drinks or any other kind of beverages is not the only thing that creates a 'diet', you need solid food for that. 
Thus, 'dietary behaviour' would refer to taking or consuming different types of diets.
Hence, the correct option is (A).

DIRECTIONS for the question: Read the information given below and answer the question that follows.

Teams from seven states – Andhra Pradesh, Bihar, Gujrat, Madhya Pradesh, Maharashtra, Uttar Pradesh and West Bengal – are participating in the national basketball championship. After the inauguration ceremony, the reporter from 11 Sports spoke to nine players – Akshay Kumar, Anil Thakur, David D’Souza, Jayesh Patel, Rahul Jha, Rajeev Sinha, Ramesh Nayudu, Sachdev Sharma and Subhash Divyundu – from these seven teams. Additional information about the interviews is as follows.

  • Each player interviewed wore a jersey with a unique number.
  • David D’Souza with jersey number 31 plays for Andhra Pradesh and is also known as a 3-pointer.
  • Rajeev Sinha with jersey number 23 is the eldest player and Subhash Divyundu is the heaviest player.
  • Sachdev Sharma has jersey number 30, while Jayesh Patel has jersey number 40.
  • Rahul Jha is one of the dunkers and he is from West Bengal.
  • The player from UP and one player from Andhra Pradesh have single digit jersey numbers.
  • Both the players with jersey numbers 40 and 34 play for Gujrat.
  • Rahul Jha was interviewed after Ramesh Nayudu, but was not the last player to be interviewed.
  • Both the players from Andhra Pradesh were interviewed one after the other and they were followed by both players from Gujrat.

  • The heaviest player has jersey number 34.
  • Ramesh Nayudu is a passer for Andhra Pradesh.
  • Jersey numbers 2 and 3 were the only single digit jersey numbers.
  • The player from Maharashtra was interviewed 7th.

Q. If David D’Souza was the first to be interviewed, who could not be interviewed 2nd?

Detailed Solution for CAT Practice Test - 8 - Question 27

We can collate the given information as follows:

  • David, the 3-pointer, plays for AP and wears jersey number 31.
  • Ramesh, the passer, plays for AP and wears jersey number 2 or 3.
  • Jayesh plays for GJ and wears jersey number 40.
  • Subhash, the heaviest player, plays for GJ and wears jersey number 34.

  • Rahul, the dunker, plays for WB.
  • The player from UP wears jersey number 2 or 3.
  • Sachdev wears jersey number 30.
  • David plays for AP.

Since the players from AP are interviewed one after the other, the 2nd player to be interviewed must be from AP.
So, the 2nd player is Ramesh, who is a passer and wears jersey number 2 or 3.
So, Rahul or Rajeev, who is the eldest player, cannot be interviewed 2nd.

Q. If Anil Thakur, Akshay Kumar and Sachdev Sharma were players who got interviewed in order, then who will not be wearing Jersey number 2?

Detailed Solution for CAT Practice Test - 8 - Question 28

We can collate the given information as follows:

  • David, the 3-pointer, plays for AP and wears jersey number 31.
  • Ramesh, the passer, plays for AP and wears jersey number 2 or 3.
  • Jayesh plays for GJ and wears jersey number 40.
  • Subhash, the heaviest player, plays for GJ and wears jersey number 34.
  • Rajeev, the eldest player, plays for BR and wears jersey number 23.
  • Rahul, the dunker, plays for WB.
  • The player from UP wears jersey number 2 or 3.
  • Sachdev wears jersey number 30.
  • Ramesh could wear jersey number 2.
  • Sachdev with jersey number 30 could play for MH or MP.

All figures are given for a population of 1000 i.e., electricity purchased per 1000 population, or number of connections per 1000 population. Population of the city has been increasing @ 20% every 10 years. Transmission losses are taken as 12% of electricity purchased. Except transmission losses all losses are considered as theft of electricity.  1 MWH = 1000 KWH. There is only one connection per family.

Q. What is the average electricity consumption per month per connection in 2000, as per the billing data?

Detailed Solution for CAT Practice Test - 8 - Question 33

Monthly billing per 1000 persons = 40 MWH = 40000 KWH

Number of connections per  1000 persons = 180

Average consumption per connection = 40000/180 = 222.2.

Hence, [4]

CAT Practice Test - 8 - Question 34

DIRECTIONS for the question: Study the following Graph & table given below and answer the question that follows.

The table below shows the power purchased, billing of power and number of connections of a power distribution company for different years in a particular city. All figures are given for a population of 1000 i.e., electricity purchased per 1000 population, or number of connections per 1000 population. Population of the city has been increasing @ 20% every 10 years. Transmission losses are taken as 12% of electricity purchased. Except transmission losses all losses are considered as theft of electricity.  1 MWH = 1000 KWH. There is only one connection per family.

Q. What percent increase is there in total electricity theft from 1980 to 2000?

Detailed Solution for CAT Practice Test - 8 - Question 34

Electricity theft = electricity purchased - transmission loss - electricity billed

► Theft in 2000 = 55 - (55 × 0.12) – 40 = 8.4 MWH/1000 persons

► Theft in 1980 = 42 - (42 × 0.12) – 30 = 6.96 MWH/1000 persons
Assuming population in 1980 as 1000X thousands,
Population in 2000 = 1.2 × 1.2 × 1000X = 1440X

► Total theft in  1980 - 6.96X

► Total theft in 2000 = 8.4 × 1.44 × X = 12.096X

Hence, percentage increase   =   74%.

Q's pet is not adjacent to R's pet but it is one of the two pets between R's and V's pets.

Q. Whose among the following can be pet no. 2?

Detailed Solution for CAT Practice Test - 8 - Question 37

From (iii) we get that T's pet and Q's pet are immediately next to each other from (iv), we get V' pet is no. 3 or 4 or 5.

From (V), we know that there are two pets between R's and V's pets and that Q's  pet is adjacent to V. Further, since Q's pet is adjacent to V. Further, since Q's pet and T's pet should be together, the orders should be RTQV or VQTR, if it is RTQV, the right most position V's pet can occupy is no. 5 and hence, R will be the second pet.

From condition (ii), S's pet should be in no. 1 position, 6th pet will be P's, which will not satisfy condition (i) So, RTQV is not possible.

We have only VQTR. Since S's pet is on the left side of R's pet, only P's and U's pet can then come to the right. But then condition (i) will not be satisfied. So we should ensure R's pet is in the right most position which means VQTR will be in 4th, 5th, 6th, 7th houses. To satisfy conditions i) and (ii), we need to have S's pet in the first place. Thus, P's and U's pets will be in 2nd and 3rd position in any order.

DIRECTIONS for the question: Analyse the graph/s given below and answer the question that follows.

Given below are two graphs giving information about the number of rallies held by some political in India from 1995-2001 and the money spent by them on these rallies over the period.

Q. The Indian government has imposed restriction that from the year 2002 there would not be more than 650 rallies in totality by all the parties. There are 4 parties other than Kongress, PJB and Semata P. These three have been allotted a share of maximum 63%, based on their seniority. If, after their allotment and respective acceptance, the remaining rallies can be distributed amongst other parties, the rallies held by each one of them in 2002 based on this distribution would be: (Assume each decides to hold -rallies based on average growth numbers per year from 1995-2001 only.)

Detailed Solution for CAT Practice Test - 8 - Question 42

63% share of 650 rallies ≈ 410.
Thus, 410 rallies are to be distributed amongst the three based on their average growth for the period gained by each one of them.
Average growth of Kongress

Thus rallies held by Kongress in 2002 = 97 + 11.2 ≈ 108 ..............(1)
Average growth of PJB

Thus rallies held by PJB in  2002 = 90 + 10.3 = 100 .....................(2)
Average growth of Semata Party

Thus, rallies held by Semata in 2002 = 78 + 9.7 ≈ 88 ......................(3)
Thus, Kongress - 108, PJB - 100, Semata - 88.
Hence, [1].

Given below are two graphs giving information about the number of rallies held by some political in India from 1995-2001 and the money spent by them on these rallies over the period.

Q. In the year 2002, 88 rallies will be held by Semata P. The party has to distribute the funds for holding these rallies in over 27 states evenly. How much fund should be allocated per state for rallies? (Assume each state will be holding approximately the same number of rallies and money spent on rallies was in the year 2002 was 15% more than that of the year 2000.)

Detailed Solution for CAT Practice Test - 8 - Question 43

Amount spend on rallies in 2000 = Rs. 4 crores

Amount to be spend on rallies in 2002 = (4 × 1.15) crores  = Rs. 4.6 crores

CAT Practice Test - 8 - Question 46

DIRECTIONS for the question:
Study the following Graph & table given below and answer the question that follows.

Q. Market capital of any company at a given point of time, is given by the product of number of shares of the company and the share price at that time. The market capital given in the tables are calculated on closing price. Based on this, which of the following are true?
I. The market capital of Infosys increased marginally during the day
II. Wipro's market capital growth was the highest during the day
III. At NSE, market capital of Satyam and NIIT grew at the same rate.
IV. NIIT's market cap growth was higher at BSE compared to that at NSE

Detailed Solution for CAT Practice Test - 8 - Question 46

Market Capital  = Number of shares  × share price
As, no. of shares are constant, all changes in market capital are corresponding to share price.
∴ Market capital change during the day is equivalent to change in stock price i.e., change in closing price over the opening price of any stock.
I. Infosys' price is coming down during the day implying a fall in market capital. Hence I is False

From table, growth of HCL Tech at NSE is the highest. II is not true.
III. From above table, III is true
IV. From above table, NIIT's growth at BSE is higher than that at NSE. Hence, IV is true
Hence, [3]

CAT Practice Test - 8 - Question 48

DIRECTIONS for the question:  Go through the pie chart/s given below and answer the question that follows.

In the Trankanian presidential election, if no single candidate secures a simple majority of more than 50% in the first round, then the top five candidates in terms of votes polled proceed to the next round. If no one still gets a simple majority, then the top three of that round go into the next round. If the decision is still not decisive in favour of one candidate, only the top two proceed to the (hopefully) last round. Shown below are the results of Elections '72.

Q. Candidate B made gains only at the expense of 'C and 'Others'. If all the voters in favour of candidate C voted for candidate B in Round 2, then how much percentage of the 'Others' category votes did candidate B get?

Detailed Solution for CAT Practice Test - 8 - Question 48

In Round 1, B got 22% votes
⇒  22% of 1850000 = 407000; C got 5% votes = 5% of 1850000 = 92500.

Others got 35% votes ⇒ 35% of 1850000 = 647500.

In Round 2, B got 53% votes ⇒ 53% of 2050000 = 1086500

CAT Practice Test - 8 - Question 49

DIRECTIONS for the question: Go through the pie chart/s given below and answer the question that follows.

In the Trankanian presidential election, if no single candidate secures a simple majority of more than 50% in the first round, then the top five candidates in terms of votes polled proceed to the next round. If no one still gets a simple majority, then the top three of that round go into the next round. If the decision is still not decisive in favour of one candidate, only the top two proceed to the (hopefully) last round. Shown below are the results of Elections '72.

Q. In the second round, at some additional constituencies (total votes = 140000), the ballot-boxes were sent late to the counting centre. If only 10000 votes were not in favour of B or F, then what minimum percentage of the new votes must go to candidate F in order to call for a third round?

Detailed Solution for CAT Practice Test - 8 - Question 49

In order for Round 3 to be called, candidate B must get 50% or less of the new total of (2050000 + 140000) = 2190000.

∴ 50% of 2190000 = 1095000
B already has 1086500 votes (53%), thus if it gets more than 8500 votes out of the new ballot, it gets a simple majority. Thus, in order to call for Round 3, F must get (140000 - 10000 - 8500) = 121500 votes.

► 121500/140000 @ 86.8%.
Hence, [2]

Candidates C got 5% votes = 0.05 × 1.85 = 0.0925 mn votes

Candidate D and E together got  10 + 6 = 16%

These were nullified ⇒ 16% of 1850000 = 296000 .......................(i)


Hence, [2]

CAT Practice Test - 8 - Question 51

DIRECTIONS for the question: Solve the following question and mark the best possible option.

If a3x – 2b3x = ax + 3b5x, what is the value of

Detailed Solution for CAT Practice Test - 8 - Question 51

The given expression can be rewritten as a(3x – 2) – (x + 3) = b(5x – 3x) 
⇒ a2x – 5 = b2x.

Taking log on both sides, we get log10 (a2x – 5) = log10 (b2x) ⇒ (2x – 5) log10 a = 2x log10 b
⇒ 2x log10 a – 5 log10 a = 2x log10 b
⇒  2x log10 a – 2x log10 b = 5 log10 a

DIRECTIONS for the question:  Solve the following question and mark the best possible option.

Two circles intersect each other at C and D. Line AB is their common tangent. What is the sum of measures of ∠ACB and ∠ADB?

Detailed Solution for CAT Practice Test - 8 - Question 52

∠BAC = ∠ADC (as both intercept same arc)
∠ABC = 1/2m (arc BC) = ∠BDC
∴ ∠BAC + ∠ABC = ∠ADC + ∠BDC
Add ∠ACB to both sides,
∠BAC + ∠ABC + ∠ACB
=∠ADC + ∠BDC +∠ACB
∴ ∠ADB + ∠ACB = 1800
[ the sum of all angles of a triangle = 1800].

Hence, [1]

By selling 45 m of cloth a shopkeeper gets a profit of selling price of 15 m of cloth .Find his real profit %?(in %, in numerical value)


Detailed Solution for CAT Practice Test - 8 - Question 53

SP of 45 m =CP of 45m +SP of 15 m
SP of 45m – SP of 15 m =CP of 45 m
SP of 30 m =CP of 30m +CP of 15 m
Therefore by selling 30m he gets a CP of 30m and CP of 15m

CAT Practice Test - 8 - Question 54

DIRECTIONS for the question: Solve the following question and mark the best possible option.

Venkat borrowed Rs. 45,000 from bank at 10% compound interest. He repaid the sum in three annual instalments, which were in arithmetic progression. He ended up paying Rs. 54,000 in all. How much did he pay in the first year?

Detailed Solution for CAT Practice Test - 8 - Question 54

Let the repayments be Rs. "a – d", Rs. "a" and Rs. "a + d"
a – d + a + a + d = 54000
3a = 54000
a = 18000

The payment at the end of year 2 is Rs. 18,000.
Borrowed amount = Rs. 45,000
Amount outstanding at the end of Year 1 = (45000 × 1.1) – (18000 – d)
=31500 + d

Amount outstanding at the end of Year 2
= {(31500 + d) × 1.1} – 18000
= 34650 + 1.1d – 18000 = 16650 + 1.1d
Amount outstanding at the end of Year  3 = {(16650 + 1.1d) × 1.1} = 18000 + d
18315 + 1.21d = 18000 + d
0.21d = – 315 ⇒ d = –1500

The payments are Rs. 19500, Rs. 18000 and Rs. 16500

DIRECTIONS for the question: Solve the following question and mark the best possible option.

A typical Puneri daily diet is in the neighborhood of 2000 kcal.
1 kcal per day translates to 0.05 W.
10% is the maximum energy content available in human excreta.
Pune Municipal Corporation is planning to set up a bio-gas plant running on the excreta produced by the 31 lakh residents of Pune city. What would be the maximum rated capacity of this plant?

Detailed Solution for CAT Practice Test - 8 - Question 55

2000 kcal translates to 2000 × 0.05 = 100 W of human power.

Out of this 10% × 100 W = 10 W of power is available in excreta.

31,00,000 × 10 = 31,000,000 W of power can thus be generated.
This amounts to 31 MW.

CAT Practice Test - 8 - Question 57

DIRECTIONS for the question: Solve the following question and mark the best possible option.

If the expression x2 + 9  and x + 5 are to have a common odd factor other than 1 such that x is a natural number less than 301, then how many values of x are possible.

Detailed Solution for CAT Practice Test - 8 - Question 57

Let the required common odd factor be K, now x2 + 9 = (x + 5)2 – (10x + 16).

Now 10x + 16 must also be divisible by K, 10x + 16 = 10(x+5) – 34. So 34 must also be divisible by K. So k clearly has to be 17.

Now x + 5 is divisible by 17, so x + 5 = 17, 34, 51, 68 and so on, which gives x = 12, 29, 46, 63, 80, 97 ...284.
So there will be total 17 values.

CAT Practice Test - 8 - Question 62

DIRECTIONS for the question: Solve the following question.

It takes an HP Printer 4 more minutes than an Epson printer to print 40 pages. Working together, the two printers can print 50 pages in 6 minutes. How long will it take the HP printer to print 80 pages (in minutes, in numerical value)?


Detailed Solution for CAT Practice Test - 8 - Question 62

If it takes the Epson printer x minutes to print 40 pages, then the rates for the printers are:
HP: 40 / (x + 4)
Epson: 40 / x
HP + Epson: 50 /6

When we have two things working together, we can add their rates:
[40 / (x + 4)] + (40 / x) = (50 / 6)
Solving this, you get x = 8.

So HP printer will take 12 minutes to print 40 pages.

Hence it will take 24 minutes to print 80 pages.

CAT Practice Test - 8 - Question 63

DIRECTIONS for the question: Solve the following question and mark the best possible option.

The diagram shows square PQRS and a regular hexagon PQTUVW.

What is the size of ∠PSW?

Detailed Solution for CAT Practice Test - 8 - Question 63

∠WPQ  = 120° ( interior angle of a regular hexagon),
So ∠WPS = (360 – 120 – 90)° = 150°.

Now PW = PQ (sides of a regular hexagon) and PS = PQ (sides of a square) so PW = PS.

Therefore, triangle PSW is isosceles, therefore
2∠PSW + 150° = 180 ° 
► ∠PSW =30°/ 2
► ∠PSW = 15°.

Divide 1370 oranges in 3 parts such that 3/4 of the first part, 5/7 of the second part and 6/11 of the third part are equal. Third part is:

Detailed Solution for CAT Practice Test - 8 - Question 69

Since we need to calculate the third part and we have been given that 6/11 of the third part is equal to the other two values.

So we can start by assuming the third part to be a multiple of 11.

Thus going by the options:
Let third part= 550

Thus second part= 420 & First part=400
Sum comes out to be 1370 and this is the actual number given.

Thus our assumption is correct.
Hence option C.

The year next to 1990 having the same calendar as that of 1990 is :

Detailed Solution for CAT Practice Test - 8 - Question 70

2 different years will have the same calendar if the total number of odd days from one year to the other is 7 or multiple of 7.

► So from 1990, if we go forward, odd days in 1991–1, 1992 – 2, 1993 – 1, 1994 – 1, 1995 – 1, 1996 – 2, 1997 – 1, 1998 – 1, 1999 – 1, 2000 – 2, 2001 – 1.
Total number of odd days up to 2001= 1 + 2 + 1 + 1 + 1 + 2 + 1 + 1 + 1 + 2 + 1 = 14.

Hence 2001 will have same calendar as 1990.

CAT Practice Test - 8 - Question 71

DIRECTIONS for the question: Solve the following question
S(a, b) is a function which computes the least common multiple (LCM) of two positive integers a and b. P is a set of 12 positive integers and L(P) is the LCM of all the elements of P. If L(P) is computed by using the function S respectively, find the minimum number of times S needs to be used to compute L(P).

Detailed Solution for CAT Practice Test - 8 - Question 71

Every time we use the function S(a,b) we get the L.C.M. of a and b. Hence the total number of elements is reduced by one each time the function is applied. Since P has 12 elements the function should be used 12-1 = 11 times to reduce the values to one i.e., the L.C.M. of all the 12 elements of P.
For example , if there are four elements a1, az, a3, a4 = S(a1, S(a2 S(a3 a4))) i.e., S is used three times.

The graph of x2 + y2 = 29 and the curve xy = 10 interest at certain number of points. All these points of intersection are joined successively by line segments to form a convex polygon. Which of the following best describes the polygon thus obtained?

Detailed Solution for CAT Practice Test - 8 - Question 72

Given equation x2 + y2 = 29 is a circle with radius  units and the given equation xy = 10 is a rectangular hyperbola. The graphs of these two equations are as follows.

 

Given x2 + y2 = 29 and xy = 10

► (x+y)2 = x2 + y2 +2xy = 49
► x + y = 7 or -7   →  (i)
► (x-y)2 = x2 + y2 – 2xy = 9
► ∴ x – y = 3 or -3  →  (ii)

Form (i) and (ii), we get

► (x, y) = (5,2) or (2,5) or (-5, -2) or (-2, -5).

Distance between (5, 2) or (2, 5) = Distance between (-5, -2) and (-2, -5)   → (i)
Distance between (5, 2) and (-2, -5) = Distance between (-5, -2) and (2,5)  → (ii)
As the pairs of opposite sides are equal and (ii) > (i), i.e., adjacent sides are not equal, the points of intersection can either form a rectangle or a parallelgram, but only rectangle is given in the options.

CAT Practice Test - 8 - Question 76

N is a multiple of 72. Also, it is known that all the digits of N are different. What is the largest possible value of N?


Detailed Solution for CAT Practice Test - 8 - Question 76

We know that the number is a multiple of 72. Therefore, the number must be a multiple of both 8 and 9. 
If the number contains all the digits from 0 to 9, the sum of the digits will be 9*10/2 = 45.
Therefore, a number containing all the ten digits will be divisible by 9.
For a number to be divisible by 8, the last 3 digits should be divisible by 8.
Now, we have to find the largest possible number. Therefore, the left-most digit must be 9, the second digit from the left should be 8 and so on. 
We'll get 9876543210 as the number. However, the last 3 digits are not divisible by 8. We must try to make the last 3 digits divisible by 8 without altering the position of other numbers. '120' is divisible by 8.
Therefore, the largest number with different digits divisible by 72 is 9876543120.
