ANSWER KEY AND EXPLANATION

1. Answer (c)

Explanation

Refer the lines…... a million cinemas………balderdash - Countless……. nonsense. No mental………...their eyes

open.

2. Answer (b)

Explanation

In the first paragraph the author’s main concern is to point out that the variability among human populations regarding

sensitivity to PTC might be a trace of the evolutionary process of natural selectivity. Then, in the second paragraph

the author offers a similar suggestion about variability in earwax type. To support these assertions the author infers

that both characteristics still serve useful purposes among non-primates-from whom humans presumably evolved.

This inference is especially clear with respect to identifying bitter substance that might be toxic.

6. Answer (c) Explanation Distance between two cities is 330 km The train started from city A travelled lonely in 8:00am to 9:00am. So it covered 60km in 1st one hour(because its speed is 60km/hr) After 9:00am, both trains are moving continuously towards each other till they meet. So their relative velocity = 60 + 75 = 135km/hr Distance to cover = 330 – 60 = 270km 8:00am 9:00am 9:00am

60km 270km

A 330km B

Therefore time required to meet = distance to cover

relative speed =

270

135 = 2 hours

We have calculated the time after 9:00 am. So the meeting time will be 9:00+2hrs = 11:00am

7. Answer (c) Explanation Let the amount paid to X per week = x and the amount paid to Y per week = y Then x + y = 550 ……………..(1)

But x = 120% of y = 120𝑦

100 =

12𝑦

10 ……………….(2)

Substituting (2) in (1) we get that 12𝑦

10 + y = 550

Solving above, we get y = 250rupees

8. Answer (b) Explanation Year : 1700 1701 1702 1703 1704 1705 Odd days : 1 1 1 1 2 1 So year 1706 will have same calendar as that of 1700

9. Answer (c) Explanation According to given diagram, the shaded region should come as an adjacent side to the dot carrying side, and another adjacent side can be a plane(blank) region so 2nd answer figure is a possibility. Again as per the given unjoined question figure, 3 adjacent side can be plane(blank) region also. So 3rd answer figure is also a possible one So your answer will be 2 and 3 only

10. Answer (d) Explanation Number of gaps between 41 poles = 40 So total distance between 41 poles = 40*50 = 2000 meter = 2 km In 1 minute train is moving 2 km/minute. Speed in hour = 2*60 = 120 km/hour

19. Answer (b) Explanation The required number would be such that it leaves a remainder of 1 when divided by 3, 4, 5, or 6 and no remainder when divided by 7. Out of given option, 106 is not divisible by seven, so we can eliminate that. 309 and 400 ie 3rd and 4th options are also not divisible by 7. Remaining option, ie 301 is divisible by 7 and (301-1) = 300 is divisible by 3, 4, 5 and 6 so it will be the correct answer from given options.

20. Answer (c) Explanation There were all parrots but six means that six birds were not parrots but only pigeons and koels. Similarly, number of parrots + number of koels = 6 and Number of parrots + number of pigeons = 6. This is possible when there are 3 parrots, 3 pigeons and 3 koels i.e. 9 birds in all.

21. Answer (b) Explanation We know perimeter of square = 4(side) x length of side So Side of first square = 40/4 = 10 cm Side of second square = 32/4 = 8 cm Area of third Square = 10*10 - 8*8 = 36 cm So side of third square = 6 [because area of square = side*side] Perimeter = 4*Side = 4*6 = 24 cm

41. Answer (b) Explanation Let the number of correct answers be Y. Number of incorrect answers = (60 – Y). 4 x Y – 1 x (60 – Y) = 130 => 5Y = 190 => Y = 38

42. Answer (d) Explanation From venn diagram, we can calculate that the number of persons expected to read at least two newspapers = 12(only 2) + 8(only 2) + 5(only 2)+2(all three) = 27 total number of person surveyed = 50 Then in a population of 10000(ie, out of 10000), the number of person who read at least two newspaper

=person read atleast two out of 50

total number of person surveyed x 10000 =

27

50 x 10000 = 5400

43. Answer (a) Explanation The smallest number in the series is 1000, a 4-digit number. The largest number in the series is 4000, the only 4-digit number to start with 4. The left most digit (thousands place) of each of the 4 digit numbers other than 4000 can take one of the 3 values 1 or 2 or 3.

The next 3 digits (hundreds, tens and units place) can take any of the 5 values 0 or 1 or 2 or 3 or 4. Hence, there are 3 x 5 x 5 x 5 or 375 numbers from 1000 to 3999. Including 4000, there will be 376 such numbers.

44. Answer (c) Explanation Clearly, A’s new position is 15th from the left. But this is the same as B’s earlier position which is 9th from the right. So, 15+9-1=23 is the total number of boys in the row And the new position of B is 9+4(boys in between A and B)+1= 14th from the right end

58. Answer (b) Explanation let us assume that john’s salary was initially 100rupees First it is decreased by 50%, ie now he is getting 100-(50% of 100) = 50rupees Subsequently it is increased by 50%, ie now 50+(50% of 50) = 75rupees So the resultant change in salary is 100 – 75 = 25 rupees Since we made our assumption that his initial salary was 100, this 25 rupees corresponds to 25%

Or for two subsequent increase or decrease of percentages we can use this formula

x + y + 𝑥𝑦

100 here x = -50%(minus because of decrease)

Y =+50%(plus because of in crease)

x + y + 𝑥𝑦

100 = -50 + 50 +

−50 x 50

100 = -25% which means that 25% loss in salary.

Given if 1 is absent rest of people can be divided into 6 equal parts i.e (x-1)/6.........(1) And given if 2 are absent rest of people can be divided into 7 equal parts i.e (x-2)/7.....(2) From (1)&(2), we get (x-1)/6 = (x-2)/7) + 1 => x = 37.

63. Answer (c) Explanation Increased average age of 8 men is 2 years. So the total increased age is 8 x 2 = 16 Women came in place of this replaced men has got an age of 20 and 24 years So the total age of 2 women will be 20+24+16 = 60

Thus the average age of women will be 60

2 = 30years

64. Answer (c) Explanation Suppose there are all the pigeons then total no of heads are 340 and total no of legs are 680. Now, since 380 (1060-680) legs are extra, it means there will be 190 (380/2) rabbits. As we know a rabbit has two extra legs than that of a pigeon. therefore number of rabbits =190 and number of pigeons = 340- 190 = 150 then the difference between their numbers is 190-150 = 40

65. Answer (b) Explanation Ratio of times taken by Sakshi and Tanya = 125 : 100 = 5 : 4. Suppose Tanya takes x days to do the work.

According to above diagram, conclusion 3 “some vertebrates are mammals” only follows

78. Answer (a) Explanation We are given three statements: Grass is greener than leaf. (G>L) Chili is greener than grass. (C>G) Combining the two statements we get: (C>G>L) Leaf is not greener than melon. This means that leaf is either equal in greenness to melon or is lower. Thus, we cannot say anything about melon’s position in sequence. Option (a) is correct as we can see that Chili is greener than leaf. Option (b) and option (d) are incorrect as nothing can be said about melon’s position in sequence. Option (c) is also incorrect as leaf and melon both could be least green of all objects.

79. Answer (c) Explanation According to data given, we can draw the venn diagram as follows

So that the total number of students enrolled for any of the two courses are 13 + 9 + 32 = 54 So number of students who are not enrolled in either course is 78 – 54 = 24

80. Answer (c) Explanation Angle between digit 3 and 8 of the clock is 150degree From 3 ’o’ clock, the hour hand would have moved for 40minutes

Hour hand will move 1

2 degrees in one minute. Therefore,

1

2 x 40 = 20degree movement is there for hour hand.

So the angle between two hands will be 150 – 20 = 130 degree
