CAT Practice Test - 2 - Question 1

Read the following passage and answer the questions that follows:
The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihoods of success, making a decision, and only then taking action to implement the decision. Rather, in their day-by-day tactical manoeuvres, these senior executives rely on what is vaguely termed “intuition” to manage a network of interrelated problems that require them to deal with ambiguity, inconsistency, novelty, and surprise; and to integrate action into the process to thinking.
Generations of writers on management have recognized that some practicing managers rely heavily on intuition. In general, however, such writers display a poor grasp of what intuition is. Some see it as the opposite of rationality; others view it as an excuse for capriciousness.
Isenberg’s recent research on the cognitive processes of senior managers reveals that managers’ intuition is neither of these. Rather, senior managers use intuition in at least five distinct ways. First, they intuitively sense when a problem exists. Second, managers rely on intuition to perform well-learned behaviour patterns rapidly. This intuition is not arbitrary or irrational, but is based on years of painstaking practice and hands-on experience that build skills. A third function of intuition is to synthesize isolated bits of data and practice into an integrated picture, often in an “Aha!” experience. Fourth, some managers use intuition as a check on the results of more rational analysis. Most senior executives are familiar with the formal decision analysis models and tools, and those who use such systematic methods for reaching decisions are occasionally leery of solutions suggested by these methods which run counter to their sense of the correct course of action. Finally, managers can use intuition to bypass in-depth analysis and move rapidly to engender a plausible solution. Used in this way, intuition is an almost instantaneous cognitive process in which a manager recognizes familiar patterns.
One of the implications of the intuitive style of executive management is that “thinking” is inseparable from acting. Since managers often “know” what is right before they can analyze and explain it, they frequently act first and explain later. Analysis is inextricably tied to action in thinking/acting cycles, in which managers develop thoughts about their companies and organizations not by analyzing a problematic situation and then acting, but by acting and analyzing in close concert.
Given the great uncertainty of many of the management issues that they face, senior managers often instigate a course of action simply to learn more about an issue. They then use the results of the action to develop a more complete understanding of the issue. One implication of thinking/acting cycles is that action is often part of defining the problem, not just of implementing the solution.

Q. According to the passage, senior managers use intuition in all of the following ways EXCEPT to

Detailed Solution for CAT Practice Test - 2 - Question 1

The question requires you to recognize which of the choices is NOT mentioned in the passage as a way in which senior managers use intuition. The passage does not mention stipulating goals.

Q. The passage suggests which of the following about the “writers on management” mentioned in paragraph 2?

Detailed Solution for CAT Practice Test - 2 - Question 2

The author asserts that the writers in question “display a poor grasp of what intuition is”. The next paragraph presents a view that, according to the author of the passage, characterizes intuition more accurately than the writers on management do.

Isenberg’s research is specifically described as showing the ways in which managers use intuition. Therefore, what Isenberg correctly comprehends, and the writers in question misunderstand, is how managers use intuition, as this choice states.

CAT Practice Test - 2 - Question 3

Read the following passage and answer the questions that follows:
The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihoods of success, making a decision, and only then taking action to implement the decision.

Q. According to the passage, the classical model of decision analysis includes all of the following EXCEPT

Detailed Solution for CAT Practice Test - 2 - Question 3

The question requires you to recognize which of the choices is NOT mentioned in the passage as a component of the classical model of decision analysis. Only this choice, “action undertaken in order to discover more information about a problem,” does not appear in the passage.

CAT Practice Test - 2 - Question 4

Read the following passage and answer the questions that follows:
The majority of successful senior managers do not closely follow the classical rational model of first clarifying goals, assessing the problem, formulating options, estimating likelihoods of success, making a decision, and only then taking action to implement the decision.

Q. It can be inferred from the passage that which of the following would most probably be one major difference in behaviour between Manager X, who uses intuition to reach decisions, and Manager Y, who uses only formal decision analysis?

Detailed Solution for CAT Practice Test - 2 - Question 4

The question requires you to compare behavior based on intuition with behavior based on formal decision analysis. This choice specifies that the manager who uses intuition incorporates action into the decision-making process, but the manager who uses formal analysis does not. This distinction is made in several places in the passage.

The passage emphasizes that decision-making and actiontaking are separate steps in formal decision analysis: “making a decision, and only then taking action.” On the other hand, those who use intuition “integrate action into the process of thinking”. Again, the author mentions that in the intuitive style of management, “ ‘thinking’ is inseparable from acting”, and “action is often part of defining the problem”.

Q. The passage provides support for which of the following statements?

Detailed Solution for CAT Practice Test - 2 - Question 5

The question requires you to identify a statement that can be inferred from information in the passage but is not explicitly stated. The author asserts that intuitive managers can “move rapidly to engender a plausible solution” and that their intuition is based on “experience that builds skill”. This implies that the combination of skill and rapidity enables mangers to employ their practical experience more efficiently, as this choice states.

CAT Practice Test - 2 - Question 6

Read the following passage and answer the questions that follows:
Nearly a century ago, biologists found that if they separated an invertebrate animal embryo into two parts at an early stage of its life, it would survive and develop as two normal embryos. This led them to believe that the cells in the early embryo are undetermined in the sense that each cell has the potential to develop in a variety of different ways. Later biologists found that the situation was not so simple. It matters in which plane the embryo is cut. If it is cut in a plane different from the one used by the early investigators, it will not form two whole embryos.

A debate arose over what exactly was happening. Which embryo cells are determined, just when do they become irreversibly committed to their fates, and what are the “morphogenetic determinants” that tell a cell what to become? But the debate could not be resolved because no one was able to ask the crucial questions in a form in which they could be pursued productively. Recent discoveries in molecular biology, however, have opened up prospects for a resolution of the debate. Now investigators think they know at least some of the molecules that act as morphogenetic determinants in early development. They have been able to show that, in a sense, cell determination begins even before an egg is fertilized.

Studying sea urchins, biologist Paul Gross found that an unfertilized egg contains substances that function as morphogenetic determinants. They are located in the cytoplasm of the egg cell; i.e., in that part of the cell’s protoplasm that lies outside of the nucleus. In the unfertilized egg, the substances are inactive and are not distributed homogeneously. When the egg is fertilized, the substances become active and, presumably, govern the behavior of the genes they interact with. Since the substances are unevenly distributed in the egg, when the fertilized egg divides, the resulting cells are different from the start and so can be qualitatively different in their own gene activity.

The substances that Gross studied are maternal messenger RNA’s –products of certain of the maternal genes. He and other biologists studying a wide variety of organisms have found that these particular RNA’s direct, in large part, the synthesis of histones, a class of proteins that bind to DNA. Once synthesized, the histones move into the cell nucleus, where sections of DNA wrap around them to form a structure that resembles beads, or knots, on a string. The beads are DNA segments wrapped around the histones; the string is the intervening DNA. And it is the structure of these beaded DNA strings that guides the fate of the cells in which they are located.

Q. It can be inferred from the passage that the morphogenetic determinants present in the early embryo are

Detailed Solution for CAT Practice Test - 2 - Question 6

The second and third paragraphs of the passage indicate that morphogenetic determinants are substances in the embryo that are activated after the egg has been fertilized and that “tell a cell what to become”.

If, as the author asserts in the first paragraph, biologists have succeeded in dividing an embryo into two parts, each of which survives and develops into a normal embryo, it can be concluded that the quantity of morphogenetic determinants in the early embryo is greater than that required for the development of a single individual.

Q. The main topic of the passage is

Detailed Solution for CAT Practice Test - 2 - Question 7

In identifying the main topic of the passage, you must consider the passage as a whole.

In the first paragraph, the author provides a historical context for the debate described.

In the second paragraph, concerning when and how the determination of embryo cells takes place.

The third and forth paragraphs provide a specific example of the “Recent discoveries in molecular biology” that may lead to the resolution of that debate.

CAT Practice Test - 2 - Question 8

Read the following passage and answer the questions that follows:

And it is the structure of these beaded DNA strings that guides the fate of the cells in which they are located.

Q. According to the passage, when biologists believed that the cells in the early embryo were undetermined, they made which of the following mistakes?

Detailed Solution for CAT Practice Test - 2 - Question 8

According to the author, early investigators arrived at the conclusion that the cells of the embryo are undetermined because they “found that if they separated an invertebrate animal embryo into two parts at an early stage of its life, it would survive and develop as two normal embryos”.

However, later biologists discovered that when an embryo was cut in places different from the one used by the early investigators, it did not form two whole embryos. Because the earlier biologists apparently arrived at their conclusion without attempting to cut an embryo in different planes, it would appear that they assumed, erroneously, that different ways of separating the embryos would not affect the fate of the two embryo parts.

CAT Practice Test - 2 - Question 9

Read the following passage and answer the questions that follows:
Nearly a century ago, biologists found that if they separated an invertebrate animal embryo into two parts at an early stage of its life, it would survive and develop as two normal embryos.

And it is the structure of these beaded DNA strings that guides the fate of the cells in which they are located.

Q. It can be inferred from the passage that the initial production of histones after an egg is fertilized takes place

Detailed Solution for CAT Practice Test - 2 - Question 9

In the third paragraph, the author asserts that substances that function as morphogenetic determinants are located in the cytoplasm of the cell and become active after the cell is fertilized.

In the fourth paragraph we learn that these substances are “maternal messenger RNA’s” and that they “direct, in large part, the synthesis of histones,” which, after being synthesized, “move into the cell nucleus”.

Thus, it can be inferred that after the egg is fertilized, the initial production of histones occurs in the cytoplasm.

CAT Practice Test - 2 - Question 10

Read the following passage and answer the questions that follows:
Nearly a century ago, biologists found that if they separated an invertebrate animal embryo into two parts at an early stage of its life, it would survive and develop as two normal embryos.

Q. It can be inferred from the passage that which of the following is dependent on the fertilization of an egg?

Detailed Solution for CAT Practice Test - 2 - Question 10

Lines in the passage indicate that substances that function as morphogenetic determinants are inactive in the unfertilized egg and that when the egg is fertilized, they “become active and, presumably, govern the behavior of the genes they interact with.”

In the fourth paragraph, we learn that these substances exert their control over the fate of the cell by directing “the synthesis of histones.” Because these histones cannot be synthesized until the substances that function as morphogenetic determinants become active, and because these substances do not become active until the egg is fertilized, it can be inferred that the synthesis of the histones is dependent on the fertilization of the egg.

Q. According to the passage, the morphogenetic determinants present in the unfertilized egg cell are which of the following?

Detailed Solution for CAT Practice Test - 2 - Question 11

In his study of sea urchins, Gross “found that an unfertilized egg contains substances that function as morphogetic determinants.”

The passage asserts that the “substances that Gross studied are maternal messenger RNA’s,” and we learn that these maternal messenger RNA’s can be found in “ a wide variety of organisms”.

CAT Practice Test - 2 - Question 12

Read the following passage and answer the questions that follows:
Archaeology as a profession faces two major problems. First, it is the poorest of the poor. Only paltry sums are available for excavating and even less is available for publishing the results and preserving the sites once excavated. Yet archaeologists deal with priceless objects every day.
Second, there is the problem of illegal excavation, resulting in museum-quality pieces being sold to the highest bidder.
I would like to make an outrageous suggestion that would at one stroke provide funds for archaeology and reduce the amount of illegal digging. I would propose that scientific archeological expeditions and governmental authorities sell excavated artifacts on the open market. Such sales would provide substantial funds for the excavation and preservation of archaeological sites and the publication of results. At the same time, they would break the illegal excavator’s grip on the market, thereby decreasing the inducement to engage in illegal activities.
You might object that professionals excavate to acquire knowledge, not money. Moreover, ancient artifacts are part of our global cultural heritage, which should be available for all to appreciate, not sold to the highest bidder. I agree. Sell nothing that has unique artistic merit or scientific value. But, you might reply, everything that comes out of the ground has scientific value. Here we part company. Theoretically, you may be correct in claiming that every artifact has potential scientific value. Practically, you are wrong.
I refer to the thousands of pottery vessels and ancient lamps that are essentially duplicates of one another. In one small excavation in Cyprus, archaeologists recently uncovered 2,000 virtually indistinguishable small jugs in a single courtyard, even precious royal seal impressions known as melekh handles have been found in abundance — more than 4,000 examples so far.
The basement of museums is simply not large enough to store the artifacts that are likely to be discovered in the future. There is not enough money even to catalogue the finds; as a result, they cannot be found again and become as inaccessible as if they had never been discovered. Indeed, with the help of a computer, sold artifacts could be more accessible than are the pieces stored in bulging museum basements. Prior to sale, each could be photographed and the list of the purchasers could be maintained on the computer A purchaser could even be required to agree to return the piece if it should become needed for scientific purposes. It would be unrealistic to suggest that illegal digging would stop if artifacts were sold in the open market. But the demand for the clandestine product would be substantially reduced. Who would want an unmarked pot when another was available whose provenance was known, and that was dated stratigraphically by the professional archaeologist who excavated it?

Q. The primary purpose of the passage is to propose

Detailed Solution for CAT Practice Test - 2 - Question 12

The first paragraph identifies two major problems faced by the archaeological profession: inadequate funding and illegal digging.

The passage indicates that the author is going to suggest how to remedy both problems, thereby benefiting the archaeological profession. The author proceeds to propose allowing the sale of excavated artifacts and to explain how this would solve both problems . The author then supports the proposal by countering possible objections to it, and in the last paragraph explains how the proposal would curb illegal digging.

Thus, the way information is organized in the passage indicates that the author’s purpose is to suggest that allowing the sale of excavated artifacts would provide funds for the archaeological profession and curb illegal digging.

Q. The author’s argument concerning the effect of the official sale of duplicate artifacts on illegal excavation is based on which of the following assumptions?

Detailed Solution for CAT Practice Test - 2 - Question 15

The author’s argument concerning the effect of the official sale of duplicate artifacts on illegal excavation appears in the passage where the author predicts that such official sale would reduce the demand for “the clandestine product.”

The rhetorical question that follows indicates that the author finds it unlikely that any purchaser would prefer objects of unknown provenance to objects of known origin, or, to rephrase, the author assumes that most people would prefer to purchase objects of authenticated provenance, as this choice states.

CAT Practice Test - 2 - Question 16

Direction : Five sentences are given below, labeled A, B, C, D and E. They need to be arranged in a logical order to form a coherent paragraph/passage. From the given options, choose the most appropriate one.

A. This made me think again about my own cynicism about Web activism.

B. Dodd said that he believes that some sort of compromise on the content of the film will be reached so that young people can see the film without seeking their parent’s permission.

C. I called Christopher Dodd, the former senator who now runs the motion picture association.

D. Sure hash tags come and go but they probably make the world, the one beyond the keyboard, a better place.

E. I expected him to suggest that all the online petitioners have failed to grasp the nuance and importance of the rating system.

Detailed Solution for CAT Practice Test - 2 - Question 16

The sequence has a CEB link – the author called a person and expected him to present a particular opinion.

The person presented his own opinion and this made the author rethink his own philosophy – there is a logical flow of thought in the sequence CEBA.

And D helps conclude the sequence. It is also the rethought out opinion of the author and logically follows A.

In statement A “this made me think again” refers to Dodd’s comment.

Hence AD should come after CEB.

Option (d) is the answer.

Direction : Five sentences are given below, labeled A, B, C, D and E. They need to be arranged in a logical order to form a coherent paragraph/passage. From the given options, choose the most appropriate one.

A. These are not art galleries or the studio of an art lover, but restaurants that believe that a dash of artwork can do-up their interiors, simultaneously promoting the works of an artist.

B. For over two years now, Tangerine restaurant has been promoting works of artists who are looking for a platform or budding artists who needs to add to their collection.

C. Restaurants in the city are converting their walls into an exhibition space, displaying the works of different budding artists periodically.

D. The once plain walls here have a new aura as frames holding different colours, themes and mediums adorn them.

E. The works are exhibited on a no-cost basis, but the select works do go through “some amount of objective judging”, by Illango’s Artspace.

Detailed Solution for CAT Practice Test - 2 - Question 17

DA is a mandatory pair as “the once plain walls” of D can be linked to “these are not art galleries” of A. This negates options (c) and (d).

CB is another mandatory pair as “restaurants in the city” in C can be linked to the specific example of “Tangerine restaurant” in B. This negates option (b).

CAT Practice Test - 2 - Question 18

Direction : Five sentences are given below, labeled A, B, C, D and E. They need to be arranged in a logical order to form a coherent paragraph/passage. From the given options, choose the most appropriate one.

C. Ironically, Manipur has many activist groups led by women.
D. True empowerment will only happen when women enter the assembly in good numbers.
E. Conflict Widows’ Forum is a group made up of women who have lost their husbands to civil violence in the state.

Detailed Solution for CAT Practice Test - 2 - Question 18

The ‘It’ in A refers to the forum in E. EA forms a mandatory pair and this helps rule out option (b).

Option (a) can be ruled out because C does not follow B; however, B can be used to substantiate C – as done in option (d).

Option (c) can be ruled out for the same reason as B is cited as an example and it follows C.

Option (d) is the answer as C .

CAT Practice Test - 2 - Question 19

Direction : In order to form a coherent paragraph, find the odd sentence from the given set of sentences.

A. This is the country where the leader of the ruling party, the speaker of the lower house of parliament, at least three chief ministers, and a number of sports and business icons are women.

B. It is also a country where a generation of newly empowered young women are going out to work in large number than ever before.

C. It's early days yet, but one hopes these are the first stirrings of change.

D. Trust Law, a news service run by Thomson Reuters, has ranked India as the worst G20 country in which to be a woman.

Detailed Solution for CAT Practice Test - 2 - Question 19

D, A and C makes up a complete story about the country being the worst for women in spite of the facts presented in A and C.

Since there is no connection between this and the “stirrings of change” in C, it is the odd sentence.

CAT Practice Test - 2 - Question 20

Direction : In order to form a coherent paragraph, find the odd sentence from the given set of sentences.

A. For no apparent reason you cannot help yourself from humming or singing a tune by Lady Gaga or Coldplay, or horror upon horrors, the latest American Idol reject.

B. Songs that get stuck in your head and go round and round, sometimes for days, sometimes for months.

C. Some people call them earworms.

D. It there was nothing unique about them they would be swamped by all the other memories that sound similar too.

Detailed Solution for CAT Practice Test - 2 - Question 20

Arranging sentences B, C and A (better than CBA) in that order explains what are “earworms” – Their uniqueness is beside the point even contrary to statement A.

Hence D is the odd sentence.

Direction for question : A paragraph is given below from which the last sentence has been deleted. From the given options, choose the one that completes the paragraph in the most appropriate way.

“Day break” marks the completion of tunneling from two opposite faces. Conventionally, the tunneling work is conducted from both ends of the tunnel. But this being a very long tunnel, Railways decided to engage in simultaneous working at more than two faces by constructing a shaft towards the North end and an adit towards the South end.

Detailed Solution for CAT Practice Test - 2 - Question 21

The paragraph discusses the speeding up of the tunneling work.

Option (a) follows the logical flow by discussing the result of speeding up the work.

Option (b) could have introduced the paragraph but it does not come in logically after the penultimate sentence.

Option (c) is incorrect as it specifies the name of the tunnel and discusses a road for emergencies – both are beyond the scope of the information in the paragraph.

Option (d) deviates from the central idea –the discussion is about the speeding up of work and not about the material used in building the tunnel.

CAT Practice Test - 2 - Question 22

Direction for question : A paragraph is given below from which the last sentence has been deleted. From the given options, choose the one that completes the paragraph in the most appropriate way.

Musharraf has said the scientists were given wide latitude to develop the nuclear program and worked in secret even from top officials. That secrecy also has raised fears that nuclear workers may have transferred technology or equipment to terrorists, either for money or ideological sympathy.
Experts say centrifuge technology would not be of much use to terror groups, who probably could not set up the vast facilities required to enrich useful quantities of uranium, with hundreds of technicians needed to run thousands of centrifuges.

Detailed Solution for CAT Practice Test - 2 - Question 22

The paragraph states the fear that nuclear technology could have been transferred to terrorists. However, the paragraph then changes its tone and states that experts feel that even if this were true, the technology would not be useful to terrorist groups who would need more resources. The penultimate line before the blank indicates that it will be probably impossible for terror groups to take advantage of any leaks in information or even receipt of equipment.

Option (c) substantiates this by saying that it is difficult for countries themselves to gather the resources needed.

Option (a) is incorrect as it brings attention to an irrelevant detail.

Option (b) is out of context as the paragraph is not concerned with the amount of uranium that has been produced by Pakistan.

CAT Practice Test - 2 - Question 23

Read the following passage and answer the questions that follows:
Federal efforts to aid minority businesses began in the 1960’s when the Small Business Administration (SBA) began making federally guaranteed loans and government sponsored management and technical assistance available to minority business enterprises. While this program enabled many minority entrepreneurs to form new businesses, the results were disappointing, since managerial inexperience, unfavorable locations, and capital shortages led to high failure rates. Even 15 years after the program was implemented, minority business receipts were not quite two percent of the national economy’s total receipts. Recently federal policymakers have adopted an approach intended to accelerate development of the minority business sector by moving away from directly aiding small minority enterprises and toward supporting larger, growth-oriented minority firms through intermediary companies. In this approach, large corporations participate in the development of successful and stable minority businesses by making use of government-sponsored venture capital. The capital is used by a participating company to establish a Minority Enterprise Small Business Investment Company or MESBIC. The MESBIC then provides capital and guidance to minority businesses that have potential to become future suppliers or customers of the sponsoring company.
MESBIC’s are the result of the belief that providing established firms with easier access to relevant management techniques and more job-specific experience, as well as substantial amounts of capital, gives those firms a greater opportunity to develop sound business foundations than does simply making general management experience and small amounts of capital available. Further, since potential markets for the minority businesses already exist through the sponsoring companies, the minority businesses face considerably less risk in terms of location and market fluctuation. Following early financial and operating problems, sponsoring corporations began to capitalize MESBIC’s far above the legal minimum of $500,000 in order to generate sufficient income and to sustain the quality of management needed. MESBIC’s are now emerging as increasingly important financing sources for minority enterprises.
Ironically, MESBIC staffs, which usually consist of Hispanic and Black professionals, tend to approach investments in minority firms more pragmatically than do many MESBIC directors, who are usually senior managers from sponsoring corporations. The latter often still think mainly in terms of the “social responsibility approach” and thus seem to prefer deals that are riskier and less attractive than normal investment criteria would warrant. Such differences in viewpoint have produced uneasiness among many minority staff members, who feel that minority entrepreneurs and businesses should be judged by established business considerations. These staff members believe their point of view is closer to the original philosophy of MESBIC’s and they are concerned that, unless a more prudent course is followed, MESBIC directors may revert to policies likely to re-create the disappointing results of the original SBA approach.

Q. Which of the following best states the central idea of the passage?

Detailed Solution for CAT Practice Test - 2 - Question 23

The passage begins by indicating that the results of the SBA approach to aiding minority entrepreneurs “were disappointing” . The passage states that “MESBIC’s are now emerging as increasingly important financing sources for minority enterprises.” Much of the passage is devoted to supporting the author’s view that MESBIC have the greater potential for success, and the last sentence in the passage confirms this view.

CAT Practice Test - 2 - Question 26

Directions: Read the following passage and answer the questions.
Anthropology is the whole history of man as fired and pervaded by the idea of evolution. Man in evolution - that is the subject in its full reach. Anthropology studies man as he occurs at all known times. It studies him as he occurs in all known parts of the world. It studies him body and soul together - as a bodily organism, subject to conditions operating in time and space, which bodily organism is in intimate relation with a soul-life, also subject to those same conditions. Having an eye to such conditions from first to last, it seeks to plot out the general series of the changes, bodily and mental together, undergone by man in the course of his history. Its business is simply to describe. But, without exceeding the limits of its scope, it can and must proceed from the particular to the general; aiming at nothing less than a descriptive formula that shall sum up the whole series of changes in which the evolution of man consists.
That will do, perhaps, as a short account of the ideal scope of anthropology. Being short, it is bound to be rather formal and colourless. To put some body into it, however, it is necessary to breathe but a single word. That word is: Darwin.
Anthropology is the child of Darwin. Darwinism makes it possible. Reject the Darwinian point of view, and you must reject anthropology also. What, then, is Darwinism? Not a cut-and-dried doctrine. Not a dogma. Darwinism is a working hypothesis. You suppose something to be true, and work away to see whether, in the light of that supposed truth, certain facts fit together better than they do on any other supposition. What is the truth that Darwinism supposes? Simply that all the forms of life in the world are related together; and that the relations manifested in time and space between the different lives are sufficiently uniform to be described under a general formula, or law of evolution.
This means that man must, for certain purposes of science, toe the line with the rest of living things. And at first, naturally enough, man did not like it. He was too lordly. For a long time, therefore, he pretended to be fighting for the Bible, when he was really fighting for his own dignity. This was rather hard on the Bible, which has nothing to do with the Aristotelian theory of the fixity of species; though it might seem possible to read back something of the kind into the primitive creation-stories preserved in Genesis. Now-a-days, however, we have mostly got over the first shock to our family pride. We are all Darwinians in a passive kind of way. But we need to darwinize actively. In the sciences that have to do with plants, and with the rest of the animals besides man, naturalists have been so active in their darwinizing that the pre-Darwinian stuff is once for all laid by on the shelf. When man, however, engages on the subject of his noble self, the tendency still is to say: We accept Darwinism so long as it is not allowed to count, so long as we may go on believing the same old stuff in the same old way.
How do we anthropologists propose to combat this tendency? By working away at our subject, and persuading people to have a look at our results. Once people take up anthropology, they may be trusted not to drop it again. It is like learning to sleep with your window open. What could be more stupefying than to shut yourself up in a closet and swallow your own gas? But is it any less stupefying to shut yourself up within the last few thousand years of the history of your own corner of the world, and suck in the stale atmosphere of its own self-generated prejudices? Or, to vary the metaphor, anthropology is like travel. Everyone starts by thinking that there is nothing so perfect as his own parish. But let a man go aboard ship to visit foreign parts, and, when he returns home, he will cause that parish to wake up.

Which of the following is NOT true according to the passage?

Refer to the data below and answer the questions that follow.
In a year prior to the Olympics, all the participating athletes were required to undergo dope tests conducted by the Anti-Doping Association.
The tests of the athletes were done five times. The first test was done in February, the second in April, the third in August, the fourth in October, and the fifth in December. Only the athletes who passed the test in February were eligible for the test in April. Only those who passed the test in April were eligible for the test in August and those who passed in August were tested in October, and so on so forth.
During a test, an athlete was tested for the presence of exactly one of the five banned substances - A, B, C, D or E. An athlete already tested for the presence of a particular substance was not tested for the presence of the same substance in subsequent test(s) during the year.
The table given below shows the number of athletes tested in each of the five months for the different banned substances. Finally, only 91 athletes passed the tests, and were cleared to participate in the Olympics. An athlete is said to pass the test conducted for the presence of a banned substance, when that particular banned substance is not detected in the blood sample of the athlete.

Q. How many athletes were tested for the presence of exactly one banned substance?

Detailed Solution for CAT Practice Test - 2 - Question 27

Number of athletes tested for the presence of at least one banned substance = Total number athletes tested in February = 105 + 245 + 345 + 130 + 95 = 920
Number of athletes tested for the presence of at least two banned substances = Total number athletes tested in April = 75 + 100 + 87 + 100 + 68 = 430
Therefore, the number of athletes who were tested for the presence of exactly one banned substance = 920 – 430 = 490.

An athlete is said to pass the test conducted for the presence of a banned substance, when that particular banned substance is not detected in the blood sample of the athlete.

Q. Suppose
X = The number of Athletes who failed the test in February due to the presence of substance other than A.
Y = The number of Athletes who failed the test in February due to the presence of any of the five substances.
What can be the approximate minimum value of X, when expressed as a percentage of Y?

Detailed Solution for CAT Practice Test - 2 - Question 30

In Feb, total of 920 Athletes were tested, out of which 430 passed the test and underwent next round of tests in April.

Therefore Y = 920 – 430 = 490. In feb 105 athletes went test for substance A.

If all of them failed the test due to a substance other than A is 490 -105 = 385.

Therefore minimum value of X when expressed as a % of Y is 385 / 490 x 100 = 78.57%.

National Institute of Management Ranchi (NIMR) began the first year of its flagship PGP course on June 22, 2017. The institute arranged guest lectures on different subjects, namely Finance, Marketing, Operations, Systems and HR throughout the year. The guest lectures are arranged such that the number of days between the two consecutive guest lectures on the same subject is same. No two subjects had equal gap between their respective two consecutive guest lectures.
The guest lectures on all the five subjects were offered for the first time on June 28th. After that, in the year 2017, the guest lectures on different subjects were offered as per the frequency decided earlier.
It is known that three of the guest lectures on Systems were held on July 18, July 28 and September 6, three of the guest lectures on HR were held on August 12, September 11 and September 26, three of the guest lectures on Marketing were held on July 7, July 13 and July 22, three of the guest lectures on Finance were held on July 2, July 8 and July 12 and three of the guest lectures on Operations were held on July 8, July 23 and August 2.

Q. On which of the following dates was the guest lecture on Systems definitely offered?

Detailed Solution for CAT Practice Test - 2 - Question 39

Suppose we denote June 28 as ‘day 0’.
It can be seen that the guest lectures on Systems were held on days 20, 30 and 70. Therefore, the frequency of guest lectures on Systems was either 2, 5 or 10.

It can be seen that the guest lectures on HR were held on days 45, 75 and 90.
Therefore, the frequency of guest lectures on HR was either 5 or 15.
It can be seen that the guest lectures on Marketing were held on days 9, 15 and 24.

Therefore, the frequency of guest lectures on Marketing was 3.
It can be seen that the guest lectures on Finance were held on days 4, 10 and 14.

Therefore, the frequency of the guest lectures on Finance was 2.
It can be seen that the guest lectures on Operations were held on days 10, 25 and 35.

Therefore, the frequency of the guest lectures on Finance was 5.
Since the frequencies of the guest lectures on different subjects were different, following were the frequencies of the guest lectures on different subjects:

Finance: 2, Marketing: 3, Operations: 5, Systems: 10 and HR: 15.

We know that the frequency of the guest lectures on Systems was 10.

November 14 is day 139, November 15 is day 140, November 16 is day 141 and November 17 is day 142.

Therefore, the guest lecture on Systems was offered on day 140 or November 15.

It is known that three of the guest lectures on Systems were held on July 18, July 28 and September 6, three of the guest lectures on HR were held on August 12, September 11 and September 26, three of the guest lectures on Marketing were held on July 7, July 13 and July 22, three of the guest lectures on Finance were held on July 2, July 8 and July 12 and three of the guest lectures on Operations were held on July 8, July 23 and August 2.

Q. Up-to September 26 (including that day), on how many days were no guest lectures offered by NIMR?

Detailed Solution for CAT Practice Test - 2 - Question 40

Suppose we denote June 28 as ‘day 0’.
It can be seen that the guest lectures on Systems were held on days 20, 30 and 70. Therefore, the frequency of guest lectures on Systems was either 2, 5 or 10.

It can be seen that the guest lectures on HR were held on days 45, 75 and 90.
Therefore, the frequency of guest lectures on HR was either 5 or 15.
It can be seen that the guest lectures on Marketing were held on days 9, 15 and 24.

Therefore, the frequency of guest lectures on Marketing was 3.
It can be seen that the guest lectures on Finance were held on days 4, 10 and 14.

Therefore, the frequency of the guest lectures on Finance was 2.
It can be seen that the guest lectures on Operations were held on days 10, 25 and 35.

Therefore, the frequency of the guest lectures on Finance was 5.
Since the frequencies of the guest lectures on different subjects were different, following were the frequencies of the guest lectures on different subjects:

Finance: 2, Marketing: 3, Operations: 5, Systems: 10 and HR: 15.

Now all the questions can be answered.
September 26 is day 90. We have to count the natural numbers up-to 90 that are not divisible by any of the five numbers 2, 3, 5, 10 and 15. Essentially, we have to count the number of natural numbers up-to 90 that are not divisible by any of 2, 3 and 5 because all the numbers that are divisible by 10 or 15 are divisible by 5.

LCM of 2, 3 and 5 is 30. There are 6 numbers up-to 90 that are divisible by 30.

LCM of 2 and 3 is 6. There are 15 numbers up-to 90 that are divisible by 6.

LCM of 2 and 5 is 10. There are 9 numbers up-to 90 that are divisible by 10.

LCM of 3 and 5 is 15. There are 6 numbers up-to 90 that are divisible by 15. 

The number of numbers up-to 90 that are divisible by 2, 3 and 5 are 45, 30 and 18 respectively. Accordingly, we can construct the following Venn diagram for the numbers up-to 90 that are divisible by at least one of 2, 3 and 5.

The number of numbers up-to 90 that are divisible by at least one of 2, 3 and 5: 24 + 12 + 12 + 6 + 3 + 3 + 6 = 66.

Therefore, the number of numbers up-to 90 that are not divisible by any of these three numbers: 90 – 66 = 24.
Therefore, the required answer is 24.

Q. Up-to September 26 (including that day), on how many days were guest lectures on Marketing and exactly one other subject offered by NIMR?

Detailed Solution for CAT Practice Test - 2 - Question 42

Suppose we denote June 28 as ‘day 0’.
It can be seen that the guest lectures on Systems were held on days 20, 30 and 70. Therefore, the frequency of guest lectures on Systems was either 2, 5 or 10.

It can be seen that the guest lectures on HR were held on days 45, 75 and 90.
Therefore, the frequency of guest lectures on HR was either 5 or 15.
It can be seen that the guest lectures on Marketing were held on days 9, 15 and 24.

Therefore, the frequency of guest lectures on Marketing was 3.
It can be seen that the guest lectures on Finance were held on days 4, 10 and 14.

Therefore, the frequency of the guest lectures on Finance was 2.
It can be seen that the guest lectures on Operations were held on days 10, 25 and 35.

Therefore, the frequency of the guest lectures on Finance was 5.
Since the frequencies of the guest lectures on different subjects were different, following were the frequencies of the guest lectures on different subjects:

Finance: 2, Marketing: 3, Operations: 5, Systems: 10 and HR: 15.
Now all the questions can be answered.
September 26 is day 90. The frequency of the guest lectures on Marketing is 3. The frequency of guest lectures on other subjects is 2, 5, 10 and 15.

Guest lectures only on Marketing and Finance
LCM of 3 and 2 is 6. We have to look for the number of numbers up-to 90 that are divisible by 6 but not by 5, 10 or 15. There are 15 numbers up-to 90 that are divisible by 6. Out of these, 3 (30, 60 and 90) that are divisible by 5. They need to be taken out. Therefore, the number of days on which guest lectures only on Marketing and Finance were offered = 15 – 3 = 12.

Guest lectures only on Marketing and Operations
LCM of 3 and 5 is 15. The guest lectures on Marketing and Operations both will be offered after every 15 days. But the frequency of guest lectures on HR is 15. Therefore, on those days, the guest lecture on HR will also be offered. Therefore, there is no day on which guest lectures only on Marketing and Operations are offered.

Guest lectures only on Marketing and Systems
LCM of 3 and 10 is 30. We have to look for the number of numbers up-to 90 that are divisible by 30 but not by 2, 5 or 15. There are no such numbers. Therefore there is no day on which guest lectures only on Marketing and Systems are offered.

Guest lectures only on Marketing and HR
LCM of 3 and 15 is 15. We have to look for the number of numbers up-to 90 that are divisible by 15 but not by 2, 5 or 10. There are no such numbers. Therefore, there is no day on which guest lectures only on Marketing and HR are offered.
Therefore, the required number of days is 12.

Ramji Telecom, Star Tarco, Anil Electronics and Mobile Store sold mobile phones worth Rs. 29000, Rs. 35000, Rs. 32000 and Rs. 38000 respectively during this period.

Q. E-Zone sells mobiles phones worth Rs. ____.

Detailed Solution for CAT Practice Test - 2 - Question 43

Each mobile shop sold one piece of one mobile phone and two pieces of the other mobile phone that they sell. Now, Mobile Store sold mobile phones worth Rs. 38000. The only possible break up is 2 x 13000 + 12000. Therefore, Mobile Store sold 2 pieces of A9 2017 and one piece of C9 Pro.

There should be one shop that sold two pieces of C9 Pro, which would be worth Rs. 24000. The third piece should be worth (29000, 35000, 32000 or 31000) – 24000 = 5000 or 11000 or 8000 or 7000, out of which only 11000 is possible. Therefore, Star Tarco sold 2 pieces of C9 Pro and 1 piece of Note 5.

There should be one shop that sold 2 pieces of Note 5, which would be worth Rs. 22000. The third piece should be worth (29000, 32000 or 31000) – 22000 = 7000 or 10000 or 9000, out of which both 10000 and 9000 are possible.

Therefore, Anil Electronics sold (2 pieces of Note 5 and 1 piece of J2) or (2 pieces of Note 5 and 1 piece of J7).
Ramji Telecom sold (2 pieces of J2 and 1 piece of Note5) or (2 pieces of J7 Prime and 1 piece of J2).

Total increase in age = 11 x 2 = 22 months

Therefore, total age of two new members is 18 years + 20 years + 22 months or 39 years 10 months.
Age of each new member = (39 yrs + 10 months) / 2 = 19 years 11 months

CAT Practice Test - 2 - Question 51

Working together, Anil and Rambo painted a fence in 8 hours. Last year, Rambo painted the fence by himself. The year before, Anil painted it by himself, but took 12 hours less than what Rambo took. How long did Anil and Rambo take (in hours) when each was painting alone? 

Detailed Solution for CAT Practice Test - 2 - Question 51

Anil can do it in b hours, so he does 1 / b per hour. Rambo does it in t hours, so he does 1 / t per hour.

Then, working together, they can do 1 / b  + 1 / t = 1 / 8 per hour (since they took 8 hours working together).

We also know that Rambo takes 12 hours longer than Anil, so t = b + 12.

We get: 1 / b  + 1 / (b + 12) = 1 / 8
⇒ 16b + 96 = b2 + 12b
⇒ b2 - 4b - 96 = 0
(b - 12)(b + 8) = 0

Then, b = 12 and b = - 8. Now, b must be positive, so we'll ignore b = - 8.

Hence, Anil alone takes 12 hours and Rambo alone takes 24 hours.

In order to buy a Honda car, Raj borrows Rs. 1,80,000 on the condition that he would pay 7.5% interest every year. He also agrees to repay the principal in equal annual instalments over 21 years. After a certain number of years, however, the rate of interest is reduced to 7%. It is also known that at the end of the agreed period, he will have paid Rs. 2,70,900 in interest in total. For how many years does he pay at the reduced interest rate?

Detailed Solution for CAT Practice Test - 2 - Question 54

Let for n years, he pays an interest of 7.5% and for (21 - n) years, the rate of interest paid is 7%.
So,

Solving it, we get n = 7.
So, for 21 - 7 = 14 years, he pays the reduced interest rate. 

CAT Practice Test - 2 - Question 55

The profit for a private firm Anil Enterprises is given by P = x3 - 6x2 + 12x + 38, where `x` is the output quantity. How much should the firm produce to maximise the profit?

Detailed Solution for CAT Practice Test - 2 - Question 55

We need to find the maximum profit, which can be found by substituting the values given in the option in the given equation.
P = x3 - 6x2 + 12x + 38, if P = 0, that would be our answer.
   ► P (2) = 23 - 6(2)2 + 12 (2) + 38
   ► = 8 - 24 + 24 + 38 = 46
   ► P(3) = (3)3 - 6(3)2 + 12(3) + 38
   ► = 27 - 54 + 36 + 38 = 47
   ► P(4) = 43 - 6(4)2 + 12(4) + 38
   ► = 64 - 96 + 48 + 38 = 54
As x increases, the function P(x) increases. The value at which the function is maximum cannot be determined.

Detailed Solution for CAT Practice Test - 2 - Question 58

Let Smera mix c litres of the 20% solution and d litres of the 30% solution.
Thus, the following equation can be set up:
   ► 20c + 30d + 60(c + d) = 42 x 2(c + d) Or, 3d = 2c Or, c : d = 3 : 2

CAT Practice Test - 2 - Question 59

The Tiara’s shop gives a discount of 12% on a statue of laughing Buddha. Let 'p' denote the percentage, above the cost price, by which the price of the statue is marked up, so that a profit of x% can be made. It is to be noted that p is an integer and x < 100. Which of the following is not a possible value of x?

Detailed Solution for CAT Practice Test - 2 - Question 59

Let the cost price of the statue be Rs. c.
So, (c + (p / 100)c)(1 - 12 / 100) = (1 + x / 100)c
   ►​Or, (1 + p / 100)(1 - 12 / 100)
    ► = (1 + x / 100) Or, (100 + p)(100 - 12)
    ► = 100(100 + x) Or, 88p - 100x
    ► = 1200
If we go with the options by plugging in different values of x in the above equation and solve for p, we shall find that the option (3) does not give an integral value of p, whereas all the other 3 options do.
Thus, 96 is not a possible value of x.

So, we can say F(x) = f(-x).

CAT Practice Test - 2 - Question 61

In triangle DEF, points A, B and C are on the sides DE, DF and EF, respectively, such that EC = AC and CF = BC. If < D = 40°, then what is the measure of < ACB?

Detailed Solution for CAT Practice Test - 2 - Question 61


∠CEA = ∠CAE
⇒ ∠ECA = 180 - 2∠CEA

∠BCF = ∠CFB
⇒ ∠BCF = 180 - 2∠CFB

∠ECA + ∠ACB + ∠BCF = 180

∠CEA + ∠CFB = 180 - 40 = 140

∠ACB = 180 – (∠ECA + ∠BCF ) = 180 – ( 180 - 2∠CEA + 180 – 2 ∠CFB) = 100.

So, total number of factors of 3 in 24! is 8 + 2 = 10.

CAT Practice Test - 2 - Question 64

Let a1, a2, a3 ... be an AP with a common difference which is not a multiple of 3. The maximum number of consecutive terms, so that all are prime, is __________. 

Detailed Solution for CAT Practice Test - 2 - Question 64

In this type of AP, it can easily be shown that exactly one out of any 3 consecutive terms will be a multiple of 3. So, at most 3 consecutive terms can be prime. This is also true in the case when one is 3. [as 3, 5, 7 or 3, 11, 19].

Another possible series is 5, 11, 17, 23 and 29; however here, the common difference is 6, which is a multiple of 3. Hence, it cannot be considered. 

CAT Practice Test - 2 - Question 65

Rani, Shalini and Babita go out for a picnic. Rani takes along 3 cakes, Shalini takes five cakes and Babita, who did not find the time to go shopping for cakes, contributes Rs. 8. If all of them share the cakes equally, then in what respective ratio should Rani and Shalini divide the money contributed by Babita?

Detailed Solution for CAT Practice Test - 2 - Question 65

Rani`s share = 3 cakes

Shalini`s share = 5 cakes

Babita`s share = Rs. 8

Since all three share the cakes equally, so:

Share of each = 8 / 3

Part of cake that Rani gives to Babita = 3 – 8 / 3 = 1 / 3

Part of cake that Shalini gives to Babita = 5 – 8 / 3 = 7 / 3

Ratio of their contributions to Babita = 1 / 3 : 7 / 3 = 1 : 7

Therefore, Rani and Shalini should share Babita`s money in respective ratio of 1 : 7.

CAT Practice Test - 2 - Question 66

(n - 1)! (a1+ a2 + a3+ ………an) (10n -1) / 9

The sum of the given numbers = 4! (1 + 3 + 5 + 7 + 9) × 11111 = 6666600.

CAT Practice Test - 2 - Question 67

Let N = 553 + 173 – 723. N is divisible by:

Detailed Solution for CAT Practice Test - 2 - Question 67

N = 553 + 173 – 723 = (54 + 1)3 + (18 – 1)3 – 723

When N is divided by 3, we get remainders (1)3 + (- 1)3 – 0 = 0

Hence, the number N is divisible by 3.

Again N = (51 + 4)3 + 173 – (68 + 4)3

When N is divided by 17, the remainder is (4)3 + 0 – (4)3 = 0

Hence, the number is divisible by 17.

Hence, the number is divisible by both 3 and 17. 

CAT Practice Test - 2 - Question 68

Bihar State decided to award two women cricket players, who did well in World Cup. It declared to distribute Rs. 2 Cr between both of them. It is known that Sharman did exceptionally well in the World Cup and deserves more than Mishali, but does not know how much more. So, the State decided to break Rs. 2 Cr into two parts and give Sharman the bigger part. What is the chance that Sharman gets at least twice as much as Mishali?

Detailed Solution for CAT Practice Test - 2 - Question 68

Let Sharman's part be S and Mishali's part be M.
Sharman’s bigger part could be any number between Rs. 1 Cr and Rs. 2 Cr.
Now, if the bigger part is to be at least twice as much as the smaller part, it means
S ≥ 2M or S ≥ 2(2Cr – S) Or,
S ≥ 4Cr / 3
Given that S lies between Rs. 1 Cr and Rs. 2 Cr, then the probability that S lies between 4Cr/3 and 2Cr is equal to (2Cr – 4Cr / 3) / (2Cr – 1Cr) = 2 / 3.

So n = 2 numbers be 2, 3, 4, 5, 6
Sum of numbers = 2 + 3 + 4 + 5 + 6 = 20.

CAT Practice Test - 2 - Question 70

A drum contained V litres of a mixture of milk and water, with water and milk in the ratio of 2 : 3. The total volume of the mixture was increased by 60% by adding water. Next, 41.6 litres of the solution in the drum was replaced by water. If the final ratio of water and milk in the drum is 7 : 3, then find the value of V (in litres).

Detailed Solution for CAT Practice Test - 2 - Question 70

The volume of mixture in the drum = V litres

Thus, volume of water = (2 / 5)V litres

Volume of milk = (3 / 5)V litres

Volume of water in the mixture when volume of water equal to 60% of volume of mixture is added to the mixture = ((2 / 5)V + 0.6V) litres = V litres

Total volume of mixture in the drum = (V + (3 / 5)V) litres = ((8/5)V) litres

When 41.6 litres of mixture in the drum is replaced by water, volume of water in the drum = (V - 41.6 x V / (8V / 5) + 41.6) litres = (V + 15.6) litres

Volume of milk in the drum now = ((3 / 5)V - 41.6 x (3 / 5)V / ((8 / 5)V)) litres = (0.6V -15.6) litres

As the ratio of water to milk in the drum is 7 : 3, we have (V + 15.6) / (0.6V - 15.6) = 7 / 3
Or, V = 130

Hence, the initial volume of the mixture in the drum = 130 litres.

CAT Practice Test - 2 - Question 71

ABCDE is a regular pentagon. A point P is taken inside this pentagon such that ∆CDP is an equilateral triangle. What is ∠BPE ?

Detailed Solution for CAT Practice Test - 2 - Question 71


∠BCD = 108°
So, ∠BCP = 48°
ΔBPC is isosceles.
So, ∠BCP = 66°
Hence, θ = 360° - 60° - 2 x 66°
   ► θ = 360° - 60° - 132°
   ► θ = 360° - 192°
   ► θ = 168°

CAT Practice Test - 2 - Question 72

A wooden cylinder of radius 21 cm and height 28 cm is cut into four identical pieces by making two cuts perpendicular to its base. If three of the four pieces are again joined back together in their original position, then what is the total surface area ( sq.cm) of this resulting wooden block ?

Detailed Solution for CAT Practice Test - 2 - Question 72


The sum of the surface areas of BFEC and BCDA (which are rectangles)
  ► = 2 x BF x BC = 2 x 21 cm x 28 cm = 1176 cm2 ..........(1)

Total area of the flat surfaces (circular bottom and top) = 2[3 / 4 x (21)2] cm2
  ► = 2 x 3 / 4 x 22 / 7 x 21 x 21 cm2 = 2079 cm2 ..........(2)

Area of the curved surface = 3 / 4 x 2 x 21 x 28 cm2
  ► = 3 / 4 x 2 x 22 / 7 x 21 x 28 cm2 = 2772 cm2 ..........(3)

So, total surface area of the new block after adding (1), (2) and (3)
  ► = (1176 + 2079 + 2772) cm2 = 6027 cm2.

CAT Practice Test - 2 - Question 73

A bag consists of some red marbles, some blue marbles and two yellow marbles. The probability that a marble picked at random is red is 1 / 2. Also, the probability that two marbles picked simultaneously are blue is 1 / 11. How many marbles are present in the bag?

Detailed Solution for CAT Practice Test - 2 - Question 73

Let the number of marbles in the bag = 2n
Number of yellow marbles = 2
As the probability of drawing a red marble = 1 / 2, number of red marbles in the bag 
= n.
Now, number of blue marbles in the bag = 2n - n - 2 = n - 2
Thus, probability of drawing 2 blue marbles
  ► = n - 2C2nC2 = ((n - 2)(n - 3))/(2n(2n - 1)) = 1/11
  ► Or, 11(n - 2)(n - 3) = 2n(2n - 1)
  ► Or, 7n2 - 53n + 66 = 0
  ► Or, 7n2 - 42n - 11n + 66 = 0
  ► Or, 7n(n - 6) - 11(n - 6) = 0
  ► Or, (7n - 11)(n - 6) = 0 Or, n = 6 (as n is integral)
Thus, number of marbles in the bag = 2n = 2 x 6 = 12.

CAT Practice Test - 2 - Question 74

In a snooker contest, there were a few male and female participants. There was a condition that each of  participants has to play exactly one game with each of others. After the contest is over, it was noticed that  in 45 such games both the participants were female and in 190 games both the players were male. Find   the number of games in which one male and one female participated.

Detailed Solution for CAT Practice Test - 2 - Question 74

Let the total number of female participants = f

Total number of male participants = m

Number of games in which both were female participants = 45

fC2 = 45 ⇒ f(f − 1)2 = 45 ⇒ f(f − 1) = 90 ⇒ f = 10

Number of games in which both players were male participants = 190

mC2 = 190 ⇒ m(m − 1)2 = 190 ⇒ m(m − 1) = 380 ⇒ m = 20

Total number of females = 10

Total number of men = 20

Number of games in which one male and one female participated.

= 20C1 × 10C1 = 20 × 10 = 200. 

CAT Practice Test - 2 - Question 75

In a series of positive numbers, (n + 1)th term is given as t(n + 1) = tn + t(n – 1) (n > 1), where tn is the nth term of the series. If t8 = 136 and t11 = 330, then find t12.

Detailed Solution for CAT Practice Test - 2 - Question 75

t10 = t8 + t9
∴ t8 = t10 - t9 ...(i)
∴ t10 - t9 = 136

Also, t11 = t10 + t9 .... (ii)
∴ t10 + t9 = 330

Solving (i) and (ii) simultaneously, we get
2(t10) = 466
∴ t10 = 233

Now, t12 = t11 + t10 = 330 + 233
t12 = 563. 

CAT Practice Test - 2 - Question 76

A timer, having digits from 0 to 9 is replaced with a timer having digits from 0 to 4. Timers are used to count seconds. Hence, after the digit reaches a value of 4 in any position, it gets reset to zero and the digit to the left of this digit increases by 1. For example, at the completion of fourth second after the start, the counter will show 0004; but at the completion of fifth second it will show 0010. What will the counter show at the completion of 8th minute?

Detailed Solution for CAT Practice Test - 2 - Question 76

Since only digits 0 to 4 can be used, the problem boils down to conversion of the number 480 from base 10 to base 5. Hence, the answer is 0341.
