QUESTION: 1

Creativity is at once our most precious resource and our most inexhaustible one. As anyone who has ever spent any time with children knows, every single human being is born creative; every human being is innately endowed with the ability to combine and recombine data, perceptions, materials and ideas, and devise new ways of thinking and doing. What fosters creativity? More than anything else: the presence of other creative people. The big myth is that creativity is the province of great individual geniuses. In fact creativity is a social process. Our biggest creative breakthroughs come when people learn from, compete with, and collaborate with other people.

Cities are the true fonts of creativity... With their diverse populations, dense social networks, and public spaces where people can meet spontaneously and serendipitously, they spark and catalyze new ideas. With their infrastructure for finance, organization and trade, they allow those ideas to be swiftly actualized.

As for what staunches creativity, that's easy, if ironic. It's the very institutions that we build to manage, exploit and perpetuate the fruits of creativity — our big bureaucracies, and sad to say, too many of our schools. Creativity is disruptive; schools and organizations are regimented, standardized and stultifying.

The education expert Sir Ken Robinson points to a 1968 study reporting on a group of 1,600 children who were tested over time for their ability to think in out-of-the-box ways. When the children were between 3 and 5 years old, 98 percent achieved positive scores. When they were 8 to 10, only 32 percent passed the same test, and only 10 percent at 13 to 15. When 280,000 25-year-olds took the test, just 2 percent passed. By the time we are adults, our creativity has been wrung out of us.

I once asked the great urbanist Jane Jacobs what makes some places more creative than others. She said, essentially, that the question was an easy one. All cities, she said, were filled with creative people; that's our default state as people. But some cities had more than their shares of leaders, people and institutions that blocked out that creativity. She called them "squelchers."

Creativity (or the lack of it) follows the same general contours of the great socio-economic divide - our rising inequality - that plagues us. According to my own estimates, roughly a third of us across the United States, and perhaps as much as half of us in our most creative cities - are able to do work which engages our creative faculties to some extent, whether as artists, musicians, writers, techies, innovators, entrepreneurs, doctors, lawyers, journalists or educators - those of us who work with our minds. That leaves a group that I term "the other 66 percent," who toil in low-wage rote and rotten jobs — if they have jobs at all — in which their creativity is subjugated, ignored or wasted.

Creativity itself is not in danger. It's flourishing is all around us - in science and technology, arts and culture, in our rapidly revitalizing cities. But we still have a long way to go if we want to build a truly creative society that supports and rewards the creativity of each and every one of us.

QUESTION: 7

During the frigid season...if s often necessary to nestle under a blanket to try to stay warm. The temperature difference between the blanket and the air outside is so palpable that we often have trouble leaving our warm refuge. Many plants and animals similarly hunker down, relying on snow cover for safety from winter's harsh conditions. The small area between the snowpack and the ground, called the subnivium...might be the most important ecosystem that you have never heard of.

The subnivium is so well-insulated and stable that its temperature holds steady at around 32 degree Fahrenheit (0 degree Celsius). Although that might still sound cold, a constant temperature of 32 degree Fahrenheit can often be 30 to 40 degrees warmer than the air temperature during the peak of winter. Because of this large temperature difference, a wide variety of species...depend on the subnivium for winter protection.

For many organisms living in temperate and Arctic regions, the difference between being under the snow or outside it is a matter of life and death. Consequently, disruptions to the subnivium brought about by climate change will affect everything from population dynamics to nutrient cycling through the ecosystem.

The formation and stability of the subnivium requires more than a few flurries. Winter ecologists have suggested that eight inches of snow is necessary to develop a stable layer of insulation. Depth is not the only factor, however. More accurately, the stability of the subnivium depends on the interaction between snow depth and snow density. Imagine being under a stack of blankets that are all flattened and pressed together. When compressed, the blankets essentially form one compacted layer. In contrast, when they are lightly placed on top of one another, their insulative capacity increases because the air pockets between them trap heat. Greater depths of low-density snow are therefore better at insulating the ground.

Both depth and density of snow are sensitive to temperature. Scientists are now beginning to explore how climate change will affect the subnivium, as well as the species that depend on it. At first glance, warmer winters seem beneficial for species that have difficulty surviving subzero temperatures; however, as with most ecological phenomena, the consequences are not so straightforward. Research has shown that the snow season (the period when snow is more likely than rain) has become shorter since 1970. When rain falls on snow, it increases the density of the snow and reduces its insulative capacity. Therefore, even though winters are expected to become warmer overall from future climate change, the subnivium will tend to become colder and more variable with less protection from the above-ground temperatures.

The effects of a colder subnivium are complex...For example, shrubs such as crowberry and alpine azalea that grow along the forest floor tend to block the wind and so retain higher depths of snow around them. This captured snow helps to keep soils insulated and in turn increases plant decomposition and nutrient release. In field experiments, researchers removed a portion of the snow cover to investigate the importance of the subnivium's insulation. They found that soil frost in the snow-free area resulted in damage to plant roots and sometimes even the death of the plant.

Both depth and density of snow are sensitive to temperature. Scientists are now beginning to explore how climate change will affect the subnivium, as well as the species that depend on it. At first glance, warmer winters seem beneficial for species that have difficulty surviving subzero temperatures; however, as with most ecological phenomena, the consequences are not so straightforward. Research has shown that the snow season (the period when snow is more likely than rain) has become shorter since 1970. When rain falls on snow, it increases the density of the snow and reduces its insulative capacity. Therefore, even though winters are expected to become warmer overall from future climate change, the subnivium will tend to become colder and more variable with less protection from the above-ground temperatures.

The effects of a colder subnivium are complex...For example, shrubs such as crowberry and alpine azalea that grow along the forest floor tend to block the wind and so retain higher depths of snow around them. This captured snow helps to keep soils insulated and in turn increases plant decomposition and nutrient release. In field experiments, researchers removed a portion of the snow cover to investigate the importance of the subnivium's insulation. They found that soil frost in the snow-free area resulted in damage to plant roots and sometimes even the death of the plant.

QUESTION: 12

During the frigid season...if s often necessary to nestle under a blanket to try to stay warm. The temperature difference between the blanket and the air outside is so palpable that we often have trouble leaving our warm refuge. Many plants and animals similarly hunker down, relying on snow cover for safety from winter's harsh conditions. The small area between the snowpack and the ground, called the subnivium...might be the most important ecosystem that you have never heard of.

The subnivium is so well-insulated and stable that its temperature holds steady at around 32 degree Fahrenheit (0 degree Celsius). Although that might still sound cold, a constant temperature of 32 degree Fahrenheit can often be 30 to 40 degrees warmer than the air temperature during the peak of winter. Because of this large temperature difference, a wide variety of species...depend on the subnivium for winter protection.

For many organisms living in temperate and Arctic regions, the difference between being under the snow or outside it is a matter of life and death. Consequently, disruptions to the subnivium brought about by climate change will affect everything from population dynamics to nutrient cycling through the ecosystem.

The formation and stability of the subnivium requires more than a few flurries. Winter ecologists have suggested that eight inches of snow is necessary to develop a stable layer of insulation. Depth is not the only factor, however. More accurately, the stability of the subnivium depends on the interaction between snow depth and snow density. Imagine being under a stack of blankets that are all flattened and pressed together. When compressed, the blankets essentially form one compacted layer. In contrast, when they are lightly placed on top of one another, their insulative capacity increases because the air pockets between them trap heat. Greater depths of low-density snow are therefore better at insulating the ground.

Both depth and density of snow are sensitive to temperature. Scientists are now beginning to explore how climate change will affect the subnivium, as well as the species that depend on it. At first glance, warmer winters seem beneficial for species that have difficulty surviving subzero temperatures; however, as with most ecological phenomena, the consequences are not so straightforward.

QUESTION: 13

The end of the age of the internal combustion engine is in sight. There are small signs everywhere: the shift to hybrid vehicles is already under way among manufacturers. Volvo has announced it will make no purely petrol-engined cars after 2019...and Tesla has just started selling its first electric car aimed squarely at the middle classes: the Tesla 3 sells for $35,000 in the US, and 400,000 people have put down a small, refundable deposit towards one. Several thousand have already taken delivery, and the company hopes to sell half a million more next year. This is a remarkable figure for a machine with a fairly short range and a very limited number of specialised charging stations.

Some of it reflects the remarkable abilities of Elon Musk, the company's founder, as a salesman, engineer, and a man able to get the most out his factory workers and the governments he deals with...Mr Musk is selling a dream that the world wants to believe in.

This last may be the most important factor in the story. The private car is...a device of immense practical help and economic significance, but at the same time a theatre for myths of unattainable self-fulfilment. The one thing you will never see in a car advertisement is traffic, even though that is the element in which drivers spend their lives. Every single driver in a traffic jam is trying to escape from it, yet it is the inevitable consequence of mass car ownership.

The sleek and swift electric car is at one level merely the most contemporary fantasy of autonomy and power. But it might also disrupt our exterior landscapes nearly as much as the fossil fuel-engined car did in the last century. Electrical cars would of course pollute far less than fossil fuel-driven ones; instead of oil reserves, the rarest materials for batteries would make undeserving despots and their dynasties fantastically rich. Petrol stations would disappear. The air in cities would once more be breathable and their streets as quiet as those of Venice. This isn't an unmixed good. Cars that were as silent as bicycles would still be as dangerous as they are now to anyone they hit without audible warning.

The dream goes further than that. The electric cars of the future will be so thoroughly equipped with sensors and reaction mechanisms that they will never hit anyone. Just as brakes don't let you skid today, the steering wheel of tomorrow will swerve you away from danger before you have even noticed it...

This is where the fantasy of autonomy comes full circle. The logical outcome of cars which need no driver is that they will become cars which need no owner either. Instead, they will work as taxis do, summoned at will but only for the journeys we actually need. This the future towards which Ubem.is working. The ultimate development of the private car will be to reinvent public transport. Traffic jams will be abolished only when the private car becomes a public utility. What then will happen to our fantasies of independence? We'll all have to take to electrically powered bicycles.

Q.

Which of the following statements best reflects the author's argument?

Solution:

The sentence "Ms Musk is selling a dream that the world wants to believe in" in the second paragraph gives a peep into the author's scepticism. The second sentence of the third paragraph talks about "unattainable self-fulfillment". The subsequent sentences talk about how the potential car-buyer is never told of the traffic jams which will rob him of independence. Thus, the myth of independence of the private car is perpetuated.

A team of researchers from Denmark and the U.K. hoped to identify the species of animal to which the antlers once belonged by analysing collagen proteins in the samples and comparing them across the animal kingdom,

Laura Geggel reports for Live Science. Somewhat surprisingly, molecular analysis of the artifacts revealed that some combs and other material had been carved from reindeer antlers.... Given that reindeer (Rangifer tarandus) don't live in Denmark, the researchers posit that it arrived on Viking ships from Norway. Antler craftsmanship, in the form of decorative combs, was part of Viking culture. Such combs served as symbols of good health, Geggel writes. The fact that the animals shed their antlers also made them easy to collect from the large herds that inhabited Norway.

Since the artifacts were found in marketplace areas at each site it's more likely that the Norsemen came to trade rather than pillage. Most of the artifacts also date to the 780s, but some are as old as 725. That predates the beginning of Viking raids on Great Britain by about 70 years.

The passage given below is followed by four summaries. Choose the option that best captures the author's position.

North American walnut sphinx moth caterpillars (Amorpha juglandis) look like easy meals for birds, but they have a trick up their sleeves—they produce whistles that sound like bird alarm calls, scaring potential predators away. At first, scientists suspected birds were simply startled by the loud noise. But a new study suggests a more sophisticated mechanism: the caterpillar's whistle appears to mimic a bird alarm call, sending avian predators scrambling for cover. When pecked by a bird, the caterpillars whistle by compressing their bodies like an accordion and forcing air out through specialised holes in their sides. The whistles are impressively loud - they have been measured at over SO dB from 5 cm away from the caterpillar - considering they are made by a two-inch long insect.

Both Socrates and Bacon were very good at asking useful questions. In fact, Socrates is largely credited with coming up with a way of asking questions, 'the Socratic method/ which itself is at the core of the 'scientific method/ popularised by Bacon. The Socratic method disproves arguments by finding exceptions to them, and can therefore lead your opponent to a point where they admit something that contradicts their original position. In common with Socrates, Bacon stressed it was as important to disprove a theory as it was to prove one - and real-world observation and experimentation were key to achieving both aims.

QUESTION: 27

The passage given below is followed by four summaries. Choose the option that best captures the author's position.

A fundamental property of language is that it is slippery and messy and more liquid than solid, a gelatinous mass that changes shape to fit. As Wittgenstein would remind us, "usage has no sharp boundary."

Oftentimes, the only way to determine the meaning of a word is to examine how it is used. This insight is often described as the "meaning is use" doctrine. There are differences between the "meaning is use" doctrine and a dictionary-first theory of meaning. "The dictionary's careful fixing of words to definitions, like butterflies pinned under glass, can suggest that this is how language works. The definitions can seem to ensure and fix the meaning of words, just as the gold standard can back a country's currency." What Wittgenstein found in the circulation of ordinary language, however, was a free-floating currency of meaning. The value of each word arises out of the exchange. The lexicographer abstracts a meaning from that exchange, which is then set within the conventions of the dictionary definition.

QUESTION: 43

An old woman had the following assets:

(a)      Rs. 70 lakh in bank deposits

(b)      1 house worth Rs. 50 lakh

(c)      3 flats, each worth Rs. 30 lakh

(d)     Certain number of gold coins, each worth Rs. 1 lakh

She wanted to distribute her assets among her three children; Neeta, Seeta and Geeta.

The house, any of the flats or any of the coins were not to be split. That is, the house went entirely to one child; a flat went to one child and similarly, a gold coin went to one child

Q.

Among the three, Neeta received the least amount in bank deposits, while Geeta received the highest. The value of the assets was distributed equally among the children, as were the gold coins.

How much did Seeta receive in bank deposits (in lakhs of rupees)?

Solution:

Assets were divided equally among the three and so were the gold coins.
Gold coins each daughter will receive = n/3
Total Amount with each person = (210 + n)/3
Total Amount with each person – Number of gold coins = 70
One child will get the house (worth Rs. 50 lakhs). Flat can’t be given to this child as it is worth 30 lakhs and limit will be exceeded.
So, the child will get 50 lakhs (House) + 20 lakhs (Bank Deposits)
Second child will get 2 Flats (60 lakhs) + 10 lakhs (Bank Deposits)
Third child will get 1 Flat (30 lakhs) + 40 lakhs (Bank Deposits)
Neeta gets the minimum amount of Bank Deposit, so 2nd child will be Neeta
Geeta gets the maximum amount of Bank Deposit, so 3rd child will be Geeta
Seeta will be the 1st child
So, Seeta got Rs. 20 lakhs as Bank Deposit.

The house, any of the flats or any of the coins were not to be split. That is, the house went entirely to one child; a flat went to one child and similarly, a gold coin went to one child

Q.

Among the three, Neeta received the least amount in hank deposits, while Geeta received the hig: of the assets was distributed equally among the children, as were the gold coins.

How many flats did Neeta receive?


Solution:

Gold coins each daughter will receive = n/3
Total Amount with each person = (210 + n)/3
Total Amount with each person – Number of gold coins = 70
One child will get the house (worth Rs. 50 lakhs). Flat can’t be given to this child as it is worth 30 lakhs and limit will be exceeded.
So, the child will get 50 lakhs (House) + 20 lakhs (Bank Deposits)
Second child will get 2 Flats (60 lakhs) + 10 lakhs (Bank Deposits)
Neeta gets the minimum amount of Bank Deposit, so 2nd child will be Neeta.

QUESTION: 47

At a management school, the oldest 10 dorms, numbered 1 to 10, need to be repaired urgently. The  following diagram represents the estimated repair costs (in Rs. Crores) for the 10 dorms, the estimated. for any dorm, the estimated repair cost (in Rs. Crores) is an integer. Repairs with estimated cost Rs. 1 or 2 crores are  considered light repairs, repairs with estimated cost Rs. 3 or 4 are considered moderate repairs and reparis  with estimated cost Rs. 5 or 6 crores are considered extensive repair.

Further, the following are known:

  1. Odd-numbered dorms do not need light repair; even-numbered dorms do not need moderate repair and dorms, whose numbers are divisible by 3, do not need extensive repair.
  2. Dorms 4 to 9 all need different repair costs, with Dorm 7 needing the maximum and Dorm 8 needing the minimum.

Q.

Which of the following is NOT necessarily true?

Solution:

We have 10 dorms, each with some repairs needing to be done. Repair costs would be Rs. 1 crore, Rs. 2 crores, Rs. 3 crores, 4, 5 or 6 crores.
From the irritating and unnecessary chart, we can infer that 2 dorms have repair costs of Rs. 1 crore each, 1 has a cost of Rs. 2c, 3 cost Rs. 3C, one each costs Rs. 4C and Rs, 5 C, and finally two dorms take up Rs. 6 crores each. Total cost should be Rs. 34 crores.

Now, let us try to do this more visually. Even-numbered ones do not need moderate repairs – or all 4 moderate-repair dorms are odd-numbered. Likewise, all 3 light-repair ones are even-numbered.
So, odd numbered dorms - 4 moderate and one extensive
Even-numbered dorms - 3 light-repair ones and two extensive.
Dorms 4 to 9 should have all costs from Rs. 1 crore to Rs. 6 crores. Dorm 7 should see Rs. 6 crores and dorm 8 should see Rs. 1 crore.
Dorms 1, 3, 5, 9 should all have moderate numbers. So, three of them should cost RS. 3C and one should cost Rs. 4C. Dorms 4, 5, 6 and 9 should have costs 2, 3, 4, 5.
Put these two together!

Dorms 5 and 9 - Rs. 3C and Rs. 4C
Dorms 4 and 6 - Rs. 2C and Rs. 5C. Dorms that are multiples of 3 do not need extensive repair.
What does this tell us?
So, dorm 6 should cost Rs. 2C and dorm 4 should cost Rs. 5C.
What can we say about dorms 1 and 3?
Both 1 and 3 should have seen moderate costs and since one of 5 or 9 costs Rs. 4C.
Both 1 and 3 should cost Rs. 3C.
What else do we have?

Dorms 5 and 9 - Costs Rs. 3C and Rs. 4C in some order
Dorms 2 and 10 - Costs Rs. 1C and Rs. 6C in some order.
Now, let us go to the questions
Statement A has to be true. Statement B also has to be true as dorm 5 will see a cost of Rs. 3C or Rs. 4C. Statement 7 has to bne true as it sees a cost of Rs. 6C. Statement D need not be true. Dorm 10 could see a cost of Rs. 1C or Rs. 6C.
Hence, the answer is "Dorm 10 repair will cost no more than Rs. 4 Crores".

  2. Dorms 4 to 9 all need different repair costs, with Dorm 7 needing the maximum and Dorm 8 needing the minimum.

Q.

What is the total cost of repairing the odd-numbered dorms (in Rs. Crores)?​


Solution:

As per the question, number of dorms with repair cost as 3 crores = 3
Since Dorm 1 and 2 already have the repair cost as Rs. 3 crores.
So, out of Dorm 5 and 9, only one can have the repair cost as Rs. 3 crores
Total cost = 3 + 3 + 3/4 + 6 + 4/3 
= 19

6.      Tea in Cup 3 got a higher rating than that in Cup 1.

7.       The rating of tea from Wayanad was more than the rating of tea from Munnar, but less than that from Assam.

 

Q.

If cups containing teas from Wayanad and Ooty had consecutive numbers, which of the following statements may be true?​

Solution:

The choices are Cup 3 (Rating – 6) and Cup 5 (Rating – 3), Assam can’t be Cup 5 because it has a higher rating than Wayanand. So, Wayanad will be Cup 5. Munnar has a rating lesser than Wayanand. So, the only choice for Munnar is Cup 2 (Rating – 2). Assam can be Cup 1 or 3 and Darjeeling can also be Cup 1 or 3.
Option (B) seems fit.

QUESTION: 55

In an 8 X 8 chessboard a queen placed anywhere can attack another piece if the piece is present in the same row, or in the same column or in any diagonal position in any possible 4 directions, provided there is no other piece in between in the path from the queen to that piece.

The columns are labelled a to h (left to right) and the rows are numbered 1 to 8 (bottom to top). The position of a piece is given by the combination of column and row labels. For example, position c5 means that the piece is in ctn column and 5tn row.

Q.

If the queen is at c5, and the other pieces at positions c2, gl, g3, g3 and a3, how many are under attack by the queen? There are no other pieces on the board.​

Q.

If the other pieces are only at positions al, a3, b4, d7, h7 and h8, then from how many positions the queen cannot attack any of the pieces?​

Solution:

Queen cannot be placed in Columns A, B, D, and H. From the remaining columns, it has to be assessed. For e.g. COLUMN C:-> If Queen is placed in c2, it will attack h7. Further, other positions in the column c can be ruled out. Similarly, analyzing other squares, the result is as follows:
Queen can be placed in e2, f2, g2, g5 (such that the pieces on board are NOT under attack). So, there are a total of 4 such squares for the Queen.

QUESTION: 63

A high security research lap requires the researchers to set a pass key sequence Pased on the scan of the five fingers of their left hands. When an employee first joins the lap, her fingers are scanned in an order of her choice, and then when she wants to re-enter the facility, she has to scan the five fingers in the same sequence

The lap authorities are considering some relaxations of the scan order requirements, since it is observed that some employees often get locked-out because they forget the sequence.

Q.

The lab has decided to allow a variation in the sequence of scans of the five fingers so that at most two scans (out of five) are out of place. For example, if the original sequence is Thumb (T), index finger (I), middle finger (M), ring finger (R) and little finger (L) then TLMRI is also allowed, but TMRLI is not.

How many different sequences of scans are allowed for any given person's original scan?

QUESTION: 68

In a 10 km race. A, B, and C, each running at uniform speed, get the gold, silver, and bronze medals, respectively. If A beats B by 1 km and B beats C by 1 km, then by how many metres does A beat C?


Solution:

Speed of A = Sa
Speed of B = Sb
Speed of C = Sc
Time taken by A (t) to travel 10 km = 10/Sa = 9/Sb = x(As B is behind A by 1 km)
Similarly, for B and C, 10/Sb = 10/Sc
So, Sa = 10/x, Sb = 9/x and Sc = 81/10x
Calculate the distance travelled by C in the time A covers 10 km
x * (81/10x) = 8.1 km
The distance between A and C = 10 – 8.1 
= 1.9 km 
= 1900 m

Arun drove from home to his hostel at 60 miles per hour. While returning home he drove half way along the same route at a speed of 25 miles per hour and then took a bypass road which increased his driving distance by 5 miles, but allowed him to drive at 50 miles per hour along this bypass road. If his return journey took 30 minutes more than his onward journey, then the total distance traveled by him is

Solution:

Let distance from home to hostel be d.
Time taken to go from home to hostel = d/60
Time taken to drive at 25 miles from hostel to home = d/25
Time to drive through bypass = (d/2 + 5)/50
Total time taken from hostel to home = d/25 + (d/2 + 5)/50
According to the question,
d/25 + (d/2 + 5)/50 = d/60 + 30/60 (Convert time from minutes to hours)
On solving, we get d = 30
Total distance travelled = 2d + 5 
= 2(30) + 5
= 60 + 5 = 65miles

The average height of 22 toddlers increases by 2 inches when two of them leave this group. If the average height of these two toddlers is one-third the average height of the original 22, then the average height, in inches, of the remaining 20 toddlers is

Solution:

Average of 22 people = a/22
Let sum of heights of two people who left = x
From the question,
(a-x)/20 = a/22 + 2
On solving, we get x=a/33
Putting value of x in a, we get the value of a as 660
x=20
Average height of remaining 20 toddlers = (a-x)/20 = 32

Solution:

Given that the production of food grains increased by 40%.
Let initial production be y and after increase it becomes 1.4x
Per capita production of food grains increased by 27%.
Per capita income = production of foodgrains no.of people
⟹ let the initial Per capita income be x/y.
After increase it becomes 1.27[x/y].

⟹ 1.4x/? = 1.27[x/y]
⟹ ? = 1.4/1.27 × y = 1.1y
Hence there is an increase of 10% in the population of the village.

A motorbike leaves point A at 1 pm and moves towards point B at a uniform speed. A car leaves point B at 2 pm and moves towards point A at a uniform speed which is double that of the motorbike. They meet at 3:40 pm at a point which is 168 km away from A. What is the distance, in km, between A and B?

Solution:

Speed of motorbike = s
Speed of car = 2s
Distance covered by motorbike in 1 hr = s km
Motorbike takes 2hrs 40 mins to reach the point where both car and motorbike meet.
In 2 hrs 40 mins, motorbike will cover a distance of 8s/3 = 168. So, s = 63
Since, speed of car is double than motorbike. So,
Distance covered by car in 1 hr 40 mins = 2 * Distance covered by motorbike in 1 hr 40 mins
Distance covered by motorbike in 1 hr 40 mins = 105 km
Distance covered by car in 1 hr 40 mins = 210 km
So, total distance = 168 + 210 = 378 km

These three mixtures of A, B, and C, respectively, are further mixed in the proportion 4:3:2. Then the resulting mixture has

Solution:

Mixtures A, B, & C are mixed in the ratio 4 : 3 : 2
--> Let the volumes = 4k, 3k, 2k respectively
Mixtures ---- Ratio ---- Water ------ Liquid
Mixture A --- 1 : 2 ---- 4k(1/3) ---- 4k(2/3)
Mixture B --- 1 : 3 ---- 3k(1/4) ---- 3k(3/4)
Mixture C --- 1 : 4 ---- 2k(1/5) ---- 2k(4/5)

Assume k = 60 [LCM(3, 4, 5) = 60]
Volume of Liquid A = 8k/3 = 160
Volume of Liquid B = 9k/4 = 135
Volume of Liquid C = 8k/5 = 96
Volume of water = 4k/3 + 3k/4 + 2k/5 = 80 + 45 + 24 = 149

If three sides of a rectangular park have a total length 400 ft, then the area of the park is maximum when the length (in ft) of its longer side is


Solution:

Let a and b be the two sides of a rectangle.
a + 2b = 400
Area of rectangle = ab (We have to maximize it)
b = (400-a)/2
Put the value of b in area of rectangle.
a(400-a)/2 = (400a-a2)/2
On differentiating the above equation, we get
400-2a = 0 => a=200
b = 100
Area will be max when length of longer side = 200.

QUESTION: 86

Let P be an Interior point of a right-angled isosceles triangle ABC with hypotenuse AB.

If the perpendicular distance of P from each of AB, BC, and CA is 4(y2 — l) cm, then the area, In sq cm, of the triangle ABC is


Solution:

PQ = PR = PS = 4(√2-1)
CS = PR
(PC)2 = (PS)2 + (CS)2
On solving, we get, PC = 4√2(√2-1)
So, QC = PC + PQ = 4
Area of a right angled triangle = ½ * Base * Height
So, ½ * AC * BC = ½ * QC * AB
On solving, we get a = 4√2
Area of triangle = ½ * a2 
= ½ * (4√2)2
= 16

If x is a real number such that logs 5 = logs (2 + x), then which of the following is true?

Solution:

Log35 lies between 1 and 2 because Log33 = 1 and Log39 = 2
1 < Log35 < 2
So, log5(2+x) should also lie between 1 and 2
1 < log5(2+x) < 2
51 < 2+x < 52
5 < 2+x < 25
3 < x < 23
 

QUESTION: 89

Let f(x) = x2 and g(x) = 2x, for all real x. Then the value of f( f(g(x)) + g(f(x)) ) at x = 1 is

Solution:

Given that f(x) = x2 and g(x) = 2x.
We have to find the value of f(f(g(x)) + g(f(x))) at x = 1,
⟹ g(1) = 21 = 2 ; f(1) = 12 = 1
First, let us find the value of f(g(x)) + g(f(x)) at x = 1,
⟹ f(g(1)) + g(f(1)) = f(2) + g(1)
⟹ 22 + 2
⟹ 6
Therefore, f(g(1)) + g(f(1)) = 6.
The value of f(f(g(1)) + g(f(1))) = f(6)
⟹ f(6) = x2 = 62 = 36

QUESTION: 90

The minimum possible value of the sum of the squares of the roots of the equation x2 + (a + 3)x - (a + 5) = 0 is Options :

Solution:

b2 + c2 = (b+c)2 – 2bc
b+c = -(a+3) and bc = -(a+5)
b2 + c2 = (a+3)2 + 2(a+5) = a2 + 8a + 19
Min value of a quadratic equation = -Discriminant (D)/4*First term
D = b2 – 4ac = 64 – 76 = -12
Min value = 12/4 = 3

if log (2a x 3b x 5c)  is the arithmatic mean  of log (26 x 3 x 57) , and log (2 x 32 x 54), then a equals


Solution:

log (2^a. 3^b. 5^c) = [log (2^2.3^3.5) + log (2^6.3.5^7) + log (2.3^2.5^4)]/3
3 * log (2^a. 3^b. 5^c) = log (2^9.3^6.5^12)
log (2^a. 3^b. 5^c)^3 = log (2^9.3^6.5^12)
log (2^3a. 3^3b. 5^3c) = log (2^9.3^6.5^12)
3a = 9
a=3

QUESTION: 94

How many different pairs (a, b} of positive integers are there such that a < b and 


Solution:

9(a + b) = ab
ab – 9a – 9b + 81 = 81
(a – 9) (b – 9) = 81 = 34
As a, b > 0 and a ≤ b, there are only 3 ordered pairs, given by a – 9 = 1, 3 or 9 and correspondingly b – 9 = 81, 27, 9.
We have to make sure that we satisfy the condition, a≤b
These are the following pairs of (a,b) that satisfy the condition
(a,b) = (10,90), (12, 36), (18,18)

QUESTION: 95

In how many ways can 8 identical pens be distributed among Amal, Bimal, and Kamal so that Amal gets at least 1 pen, Bimal gets at least 2 pens, and Kamal gets at least 3 pens?


Solution:

Number of pens that Amal gets = a+1
Number of pens that Bimal gets = b+2
Number of pens that Kamal gets = k+3
So, (a+1) + (b+2) + (k+3) = 8
a + b + k = 2
So, we get (2+3-1)C(3-1) = 6 [Based on the formula, (n+r-1)C(r-1)]

QUESTION: 96

How many four digit numbers, which are divisible by 6, can be formed using the digits 0, 2, 3, 4, 6, such that no digit is used more than once and 0 does not occur in the left-most position?


Solution:

For a number to be divisible by 6, it should have both 2 and 3 as factors.
For 3: The sum of digits should be divisible by 3
For 2: The last digit of the number should be even
There can be three such cases, (0,2,3,4), (0,2,4,6) and (2,3,4,6)
1st case: (0,2,3,4)
When the last digit is ‘0’
The number of combinations can be 3! = 6
When the last digit is 2/4
The number of combinations will be 2*2*1*2 = 8
Total = 14
2nd case: (0,2,4,6)
When the last digit is ‘0’
The number of combinations = 3! = 6
When the last digit is 2/4/6
The number of combinations = 2*2*1*3 = 12
Total = 18
3rd case: (2,3,4,6)
Last digit has to be 2/4/6
So, the number of combinations = 3*2*1*3 = 18
Total number of combinations = 14+18+18 = 50
