Directions for Questions Analyse the following passage and provide appropriate answers. An example of a scientist who could measure without instruments is Enrico Fermi (1901-1954), a physicist who won the Nobel Prize in physics in 1938. He had a Well-developed knack for intuitive, even casual sounding measurements. One renowned example of his measurement skills was demonstrated at the first detonation of the atom bomb, the Trinity Test site, on July 16, 1945, where he was one of the atomic scientists observing from base camp. While final adjustments were being made to instruments used to measure the yield of the blast, Fermi was making confetti out of a page of notebook paper. As the wind from the initial blast wave began to blow through the camp, he slowly dribbled the confetti into the air, observing how far back it was scattered by the blast (taking the farthest scattered pieces as being the peak of the pressure wave), Fermi concluded that the yield must be greater than 10 kilotons. This would have been news, since other initial observers of the blast did not know that lower limit. After much analysis of the instrument readings, the final yield estimate was determined to be 18.6 kilotons. Like Eratosthenes7 Fermi was aware of a rule relating one simple observation-the scattering of confetti in the Wind To a quantity he wanted to measure. The value of quick estimates was something Fermi was familiar with throughout his career. He was famous for teaching his students skills at approximation of fanciful-sounding quantities that, at first glance, they might presume they knew nothing about. The best-known example of such a Fermi question was Fermi asking his students to estimate the number of piano tuners in Chicago, when no one knows the answer. His students science and engineering majors-would begin by saying that they could not possibly know anything about such a quantity. Of course, some solutions would be to simply do a count of every piano tuner perhaps by looking up advertisements, checking with a licensing agency of some sort, and so on. But Fermi was trying to teach his students how to solve problems where the ability to confirm the results would not be so easy. He wanted them to figure out that they knew something about the quantity in question. Suppose you apply the same logic as Fermi applied to confetti, which of the following statements would be the most appropriate?

Directions for Questions Analyse the following passage and provide appropriate answers "Whatever actions are done by an individual in different embodiments, [s]he reaps the fruit of those actions in those very bodies or embodiments (in future existences)". A belief in karma entails, among other things, a focus on long run consequences, i.e., a long term orientation. Such an orientation implies that people who believe in karma may be more honest with themselves in general and in setting expectations in particular-a hypothesis we examine here. This research is based on three simple premises. First, because lower expectations often lead to greater satisfaction, individuals in general, and especially those who are sensitive to the gap between performance and expectations, have the incentive to and actually do strategically lower their expectations. Second, individuals with a long term orientation are likely to be less inclined to lower expectations in the hope of temporarily feeling better. Third, long term orientation and the tendency to lower expectations are at least partially driven by cultural factors. In India, belief in karma, with its emphasis on a longer term orientation, will therefore to some extent counteract the tendency to lower expectations. The empirical results support our logic; those who believe more strongly in karma are less influenced by disconfirmation sensitivity and therefore have higher expectations. Consumers make choices based on expectations of how alternative options will perform (i.e., expected utility). Expectations about the quality of a product also play a central role in subsequent satisfaction. These expectations may be based on a number of factors including the quality of a typical brand in a category, advertised quality, and disconfirmation sensitivity. Recent evidence suggests that consumers, who are more disconfirmation sensitive (i.e.,consumers who are more satisfied when products perform better than expected or more dissatisfied when products perform worse than expected) have lower expectations. However, there is little research concerning the role of culture specific variables in expectation formation, particularly how they relate to the impact of disconfirmation Sensitivity on consumer Future existences in the paragraph can refer to'.

In each of the questions below, five sentences, labeled A, B, C, D and E, are given. They need to be arranged in a logical order to form a coherent paragraph/passage. From the given options, choose the most appropriate option. (A) Instead, people tend to treat the whole concept of intelligence with concern. (B) A structural examination based on a factor analysis demonstrated that common - sense conceptions of intelligence are multifarious, containing many controversial themes, which are also typical of the hundred - year - long scientific discussions of intelligence. (C) Another characteristic which showed up in the studies was people's reluctance to give explicit definitions of intelligence. (D) This reluctance derives from a perception of the society as posing an intrinsic threat to the individual; intelligence is seen as a concept enabling hierarchical categorisation and societal control of individuals. (E) This many - sidedness is an indication of the social nature of these conceptions, which are clearly linked to social disputes and conflicts of interests.

A man starting at point A walks nine km north to reach point B, then four km east to reach point C, then three km in north direction to reach point D, then four km east to reach point E. Now he takes shortest path to point C and continues in the same direction till he reaches the point which is exactly in north direction with respect to point A. What is the shortest distance from the starting point to the destination?
Directions : Zeenal starts walking from point A. After walking 10m towards north she reaches at point B. Then she takes a left turn and walks another 16m to reach at point C. Then she takes another left turn and walks 5m and reaches at point D. Then she takes left turn again and walks 28m to reach at point F. Point E is at 12m to the west of point F.
What is the distance between point B and Point F?
To calculate distance between point B and F i. e. distance BF we can use Pythagoras theorem. (BF)2 = (BE)2 + (EF)2 = (5)2 + (12)2 = 25 + 144 = 169
Therefore BF=13 Hence option 2

Directions for Questions: Answer the following questions based on the information given below. A computer program converts a two-digit number into another number in five steps. The following example illustrates the operations on six two-digit numbers
If the input is 11, then what is the output in step 5?
To explain the step wise logic, let's take the first number of the input series; i.e. 12 Input: 12
Step-1: input is multiplied by 2 and 2 is added i.e. 12 X 2 + 02 = 26
Step-2: resultant in step-1 is divided by 2 and 2 is subtracted i.e. (26/2)-2=11
Step-3: sum of the digits of resultant of step-2 is taken i.e. 01 + 01 = 02
Step-4: sum of input and resultant of step-3 i.e. 12 + 02 = 14
Step-5: difference between the digits of resultant in step-4 i.e. 04 - 01 = 03
Input: 11
Step 1: 11 X 2 + 02 = 24
Step 2: (24/2) - 02 = 10
Step 3: 01 + 00 = 01
Step 4: 11 + 01 = 12
Step 5: 02 - 01 = 01
Hence, option 2
The questions below are based on the reasoning contained in brief statements or passages. For some questions, more than one of the choices could conceivably answer the question. However, you are to choose the best answer; that is, the response that most accurately and completely answers the question. You should not make assumptions that are by common sense standards implausible, superfluous, or incompatible with the passage. Edward Grieg: Your gallery is biased against my paintings. I have submitted twenty canvases in the last three years and you have not accepted any of them for display. You are punishing me because I won the Western Art award three years ago and your manager thought the award should have gone to his artist son. Gallery owner: You are wrong! Our acceptance standards and display policies do not discriminate against you. Our staff covers the painters’ names, so the review board does not know who the artist is when it determines which pieces of art will be accepted for display and sale. The review board would not know which paintings you submitted. Which one of the following assumptions does the gallery owner make in his reply?

In the last decade, the use of bicycle helmets has increased tremendously, particularly among young children. Although bicycle helmets appear to be as sturdy and safe as football helmets, they are exempt from the safety standards the government has imposed upon the manufacture of football helmets. As a result, a child involved in a bicycle accident is more likely to suffer a serious head injury than is a child injured in a football game. The argument depends upon which one of the following assumptions:

If top academics and those highly informed about the subject take issue with poetry, school pupils cannot be expected to fathom it. On December 7th, 2007, The Guardian, a British newspaper affiliated to the Left, noted that this ambiguous identity of poetry renders it very difficult to teach; "But until education theory asks itself what poetry itself is, and therefore what the teacher is trying to get across, poems will continue largely to figure as teaching aids, exercises and - for teenagers - increasingly tedious, somewhat arbitrary puzzles". The canonized poets and their poetry are concerned with adult life experiences, e.g. love, life, work, history and politics, solitude, loneliness, etc. For this reason, widely acclaimed poetry is deep and requires an adult mind and mature emotional depth to understand, or at least draw something from, this famous poetry.

Aviation is important, both as an industry in its own right and as a facilitator for the success and competitiveness of other industries. The success of the aviation industry is also integral to national competitiveness, economic development and social progress. More importantly, aviation supports those new economic sectors on which India's future prosperity relies, like information technology, biotechnology, finance and electronics. That India's air transport industry is on the rise is an indisputable fact. However the Indian economy will only achieve its true potential if we are able to compete in the industries of the future. We need to be strong in the areas with potential to grow and the role of India's aviation sector is critical in this regard. India needs to make massive investments in infrastructural development.

It has been suggested that with the continued advance of technology, robots will be able to replace skilled craftsmen who currently assemble and test sophisticated manufactured goods, such as musical instruments. This suggestion is based on the belief that the assembly and testing of musical instruments consists of learning a series of techniques and processes, which can be programmed automatically without any understanding of how the various parts are supposed to work together to produce a high quality musical instrument. If this were the case, then robots could be programmed to follow the techniques and processes, and craftsmen would not be needed to assemble and test the instruments. But to do their jobs, skilled craftsmen must also understand the principles of sound production, together with the nuances of tone quality and the other criteria of a high quality musical instrument. Therefore, the idea that robots will replace people in the production of musical instruments is seriously flawed.
Which one of the following selections, if true, would most seriously weaken the author’s conclusion that robots will not replace skilled craftsmen in the production of musical instruments?

The football coach at a midwestern college noticed that some of his players were frequently late to morning football practices and seemed somewhat lethargic after they did arrive. He directed his assistant coach to look into the matter. The assistant coach reported back that most of the late and less active players belonged to fraternities on campus which were renowned for their frequent and late night parties. The head coach then prohibited all of his football players from being members of fraternities. He reported that this would ensure that his players would get to practice on time and that they would have more productive practice sessions. The head coach’s reasoning is not sound because he fails to establish which one of the following:

A finishes a work in 7 days, B finishes the same job in 8 days and C in 6 days. They take turns to finish the work. A on the first day, B on the second and C on the third day and then A again and so on. On which day will the work get over?
(e)11th day
Work done by B on second day = 1/8
Work done by C on third day = 1/6
Portion of the work done after 3 days = 1/7 + 1/8 + 1/6 = 73/168
Work done after 6 days = 2 x 73/168 = 146/168
Remaining work = 22/168 = 11/84
Work done on 7th day (by A) = 1/7 = 12/84
Since 12/84 > 11/84, work will get completed on 7th day

∆ABC is right angled at A and AD is the altitude to BC. If AB = 8 and AC = 15, If M is the midpoint of BC, find AM.
by the theorem of Pythagoras.
BC2=82 + 152 =64+225=289.
Therefore, BC= √289 =17
Area of the triangle =1/2 * product of perpendicular side = ½ *8*15 =60
also, Area=1/2 *BC *AD=60 =1/2*17*AD=60
AD=120/17. Again, AM is the median to the hypotenuse.
AM=1/2 *hypotenuse = ½ *17=8.5. Hence option (b).
In the figure, ∠w + ∠z = 170°. Which of the following is (are) true?
I. ∠x > ∠y
II. ∠x and ∠z are supplementary
III. ∠x < />
Statement I is correct, since the two lines are not parallel and meet on the left. The lower line can be rotated clockwise or the top line can be rotated counter clockwise, or a combination of the two. In each case, angle x is greater than angle y.
Or ,
because vertically opposite angles
X + Z = 180o
Y + Z = 170o
Hence, X >Y From the diagram, it is clear that Z is an obtuse angle i.e greater than 90o.
Since X + Z = 180o,
X will be less than 90o .
Hence, statement III is also true.
The length of the sides of a triangle are x + 1, 9 -x and 5x -3 . The number of values of x for which the triangle is isosceles is:
Let x + 1 = 9 - x
2x = 8
X = 4
The sum of any two sides of triangle should be greater than third side
Hence, if x = 4, then sides of the triangle are 5, 5 and 17
This is invalid as the sum of (5+5) is less than 17
Let x + 1 = 5x - 3
X = 1
If x = 1, then the sides of the triangle are 2, 8, 2
This is also invalid
Let 9 - x = 5x - 3
X = 2
If x =2, then the sides of the triangle are 3, 7, 7
Hence, this is valid.
ABCD is a trapezium, such that AB, DC are parallel and BC is perpendicular to them. If ∠DAB = 45°, BC = 2 cm and CD = 3 cm then AB=
∠ADE = 45° i.e. AE = DE
In rectangle BCDE
CD = BE = 3 cm
DE = BC = 2 cm
Therefore, AE = 2 cm
AB = AE + BE = 5 cm
Directions for Questions A truck travelled from town A to town B over several days. During the first day, it covered 1/p of the total distance, where p is a natural number. During the second day, it travelled 1/q of the remaining distance, where q is a natural number. During the third day, it travelled 1/P of the distance remaining after the second day, and during the fourth day, 1/q of the distance remaining after the third day. By the end of the fourth day the truck had travelled 3/4 of the distance between A and B.
The value of p + q is
Hence, the total distance is multiple of 7 [3+4]
Hence, p + q should also be multiple of 7
Hence, option 4
A truck travelled from town A to town B over several days. During the first day, it covered 1/p of the total distance, where p is a natural number. During the second day, it travelled 1/q of the remaining distance, where q is a natural number. During the third day, it travelled 1/P of the distance remaining after the second day, and during the fourth day, 1/q of the distance remaining after the third day. By the end of the fourth day the truck had travelled 3/4 of the distance between A and B.
If the total distance is 100 kilometers, the minimum distance that can be covered on day 1 is kilometres.
Distance travelled on first day will be minimum when p is maximum i.e. p = 4
Hence, distance travelled on first day = 100/4= 25 km
Two persons are climbing up on two moving escalators which have 120 steps. The ratio of 1st person's speed to that of 1st escalator is 2:3 (steps). The ratio of 2nd person's speed to that of 2nd escalator is 3: 5 (steps). The total number of steps taken by both the persons are
This is repeated 24 times(120/5).
Hence, first person takes = 24 X 2 = 48 steps
Second person: For every 3 steps he takes, the escalator moves by 5 steps at the same time.
Hence, 8 steps are covered at a time.
This is repeated for 15 times(120/8)
Hence, second person takes = 3 X 15 = 45 steps
Total number of steps = 48 + 45 = 93
Three screws are drawn at random from a lot of 100 screws, 10 of which are defective. The probability of the event that all 3 screws drawn are non-defective, assuming that the screws are drawn without replacement, is
In a single throw of 3 dice, the probability of not getting the same number on any 2 dice is
The number on second dice should be any of the 5 numbers remaining
The number on third dice should be any of the 4 numbers remaining
Probability of not getting the same number on any 2 dice is = 
n an examination, the average marks obtained by students who passed was x%, while the average of those who failed was y%. The average marks of all students taking the exam was z%. Find in terms of x, y and z, the percentage of students taking the exam who failed.
Therefore,
Sum of all the students' marks who passed = px
Sum of all the students' marks who failed = fy
Sum of all the students' marks = tz tz = px + fy .... (1)
Also, t = p + f Multiply by x tx = px + fx .....(2)
(2-1) gives
t(x-z) = f(x-y)
Fail percentage = (f/t) = (x-z)/(x-y)
Option 1
Pipes A and B can fill a tank in 2 hours and 3 hours respectively. Pipe C can empty the tank in 4 hours. Pipe A is initially opened to fill the empty tank. After 30 minutes, Pipe B is opened. After another 30 minutes Pipe C is opened. How much longer after Pipe C is opened will it take for the tank to be full?
In 0.5 hours, A can fill 0.5/2 = 1/4 of the tank
In the next 30 minutes, 0.5 x (1/2 + 1/3) = 0.5 x 5/6 = Another 5/12 of the tank is filled
Total tank filled in 1st hour = 1/4 + 5/12 = 8/12 = 2/3rd of the tank
When all 3 pipes are opened, effective flow = 1/2 + 1/3 -1/4 = (6 + 4 - 3)/12 = 7/12
Or, In 12/7 hours, the tank will be full from being empty So, 1-2/3 = 1/3 tank will take = (1/3) x (12/7) = 4/7 hours to be full.
Therefore, 4/7 hours after Pipe C is opened, the tank will be full.
Ram goes to the supermarket and buys chocolates, chips and pastries in the ratio of 7:13:19 respectively. The cost of chips, pastries and chocolates is in the ratio 7:11:23 respectively. What percentage of the expenses in the supermarket was from chocolates?
Let the cost of the chocolates, chips and pastries be 23y, 7y, 11y respectively.
Total expenses = xy (23 x 7 + 7 x 13 + 11 x 19) percentage expenses from chocolates = 100 x (23y x 7x)/ (xy (23 x 7 + 7 x 13 + 11 x 19))
= 161 x 100/(161 + 91 + 209)
= 161 x 100/461 ~= 35%.
3 dice are thrown. What is the probability the product of the 3 numbers is less than 7?
Then product of the other 2 dice must be 6 or lesser:
Product = 1 - (1,1)
Product = 2 - (1,2),(2,1)
Product = 3 - (1,3),(3,1)
Product = 4 - (1,4),(2,2),(4,1)
Product = 5 - (1,5),(5,1)
Product = 6 - (1,6),(6,1),(2,3),(3,2)
Total = 14
Next, consider the 1st dice has 2.
Then the product of the other 2 dice must be 3 or lesser.
Product = 1 - (1,1)
Product = 2 - (1,2),(2,1)
Product = 3 - (1,3),(3,1)
Total = 5
Next, consider the 1st dice has 3.
Then the product of the other 2 dice must be 2 or lesser.
Product = 1 - (1,1) Product = 2 - (1,2),(2,1) Total = 3
If 1st dice has 4/5/6, then the product of other 2 has to be 1.
This is a total of 3 cases.
Total outcomes = 6 x 6 x 6 = 216.
Total favourable cases = 14 + 5 + 3 + 3 = 25
There are some cows, bulls and 45 hens in a group. One caretaker looks after 15 animals. The number of bulls is twice the number of cows. If the number of heads is less than the total number of feet by 186 (including the caretakers), how many caretakers are there?
It is given, b = 2a
Total number of heads = a+ b + c + 45
Total number of legs = 4a + 4b + 2c + 2 X 45 = 4a + 4b + 2c + 90
4a + 4b + 2c + 90 - (a + b + c + 45) = 186
3a + 3b + c = 141
3a + 3(2a) + c = 141
9a + c = 141
Considering the options, c is less than or equal to 9
Hence, the nearest multiple of 9 less than 141 is 135
Therefore,
C = 141 - 135 = 6
Hence, a = 15, b = 30
Total number of animals = 45 + 15 + 30 = 90
Mr. Balram has 30 currency notes consisting of dollars and rupees. If the rupees were dollars and dollars were rupees, he would have 78 rupees more than he has now. If one dollar is equal to 40 rupees, the number of dollars he has, is
p + q = 30
Let the amount be Rs X
p + 40q = X
q + 40p = X + 78
Therefore,
39p - 39q = 78
p - q = 2
Hence, p = 16 and q = 14
Hence, option 3
x, y and z are three positive integers such that x > y > z. Which of the following is closest to the product xyz?
Let x = 4, y = 3 and z = 2
xyz = 4 X 3 X 2 = 24
(x-1)yz = 3 X 3 X 2 = 18
x(y-1)z = 4 X 2 X 2 = 16
xy(z-1) = 4 X 3 X 1 = 12
x(y+1)z = 4 X 4 X 2 = 32
Only option 1 is closest to xyz
Let x = 10, y = 5 and z = 3
Xyz = 150
(x-1)yz = 9 X 5 X 3 = 135
x(y-1)z = 10 X 4 X 3 = 120
xy(z-1) = 10 X 5 X 2 = 100
x(y+1)z = 10 X 6 X 3 = 180
Hence, only option 1 is closest to xyz
A brokerage house offers 3 stock portfolios; Port-folio 1 consists of 2 blocks of common stock and 1 municipal bond. Portfolio II consists of 4 blocks of common stock, 2 municipal bonds and 3 blocks of preferred stock. Portfolio III consists of 2 blocks of common stock, 2 municipal bonds and 3 blocks of preferred stock. A customer Wants 12 blocks of common stock, 6 municipal bonds and 6 preferred stocks. How many portfolio III should be offered?
We can try with different combinations and can conclude that portfolio III offered can be zero i.e. if the number of portfolio I is 2 and number of portfolio II is 2, then the customer gets 12 blocks of common stock, 6 municipal bonds and 6 preferred stocks
In June, a football team played 60 games and won 30% of these. After a phenomenal winning streak this team raised its average to 50%. How many games did the team win in a row, to attain this average?
Number of matches lost=60-18 = 42
to have an average of 50%, the team must have an equal number of wins and losses.
So, to raise the average to 50% another 24(42-18) matches should be won.
Present ages of Seema and Naresh are in the respective ratio of 5:7. Five years hence the ratio of their ages becomes 3:4 respectively. What is Naresh's present age in years?
Given (5x+5)/(7x+5) = 3/4
20x + 20 = 21x + 15
or x = 5.
Naresh's Present age = 7x = 35.
Ram is 3 times as old as his brother. Ram's father is 3 times older than Ram. In 9 years, Ram will be 1.5 times the age of his brother. What will be the age of Ram's father when Ram is 1.5 times the age of his brother?
R = 3B
and (R + 9) = 1.5(B+9)
3B + 9 = 1.5B + 13.5
1.5B = 4.5 or B = 3 years, R = 9 years.
Fathers current age = 4R (Since father is 3 times older than Ram, his age is R + 3R, and not 3R)
Fathers age when Ram is 1.5 times the age of his brother = 4R + 9 = 45.
