This is the answer key for Set B.
Friends, each year, after the exam, there is a substantial confusion regarding answer keys – various answer keys don’t match and students are left in confusion. So this year, me and Prem Ranjan ji (IAS rank 62, cse 2013) (https://www.facebook.com/Prem.Ranjan.Singh.1985 ) have tried to come up with the following key after doing as much internet research as we could. Still there might be some grey areas and we are open for discussing these.
My personal opinion on the paper, passages I found it substantially tougher than last year.
Disclaimer: There is no guarantee for accuracy.

Q 32 5 persons fire bullet (b)
Q 33 630 students and rows (d)
Let it be 3. Means 3x + 9 = 630. Means 3x = 621. Possible as it is divisible by 3.

Q 46. Charity show (c)
Total sold = 420.
Sold at Rs. 5 = 210. Total money = 210 * 5 = 1050.
Sold at Rs 3 = 140. Total money = 140 * 3 = 420.
Sold at Rs 2 = 420 – 210 – 140 = 70. Total money = 70 * 2 = 140.
Total money = 1050 + 420 + 140 = 1610.

F = mod
G = mod
H = mod
Modern alternate years. H like G. F like E. Paper setter likes F, so likes E. Last year paper had A, so this year modern must be asked. Among modern, paper setter likes E. So E has higher chance.
Q 58. 6 women (d)
Total 6. 4 dancers, 4 vocal, 1 actress, 3 violin.
Girija = violin
Vanaja = violin, vocal
Jalaja = no violin, vocal
Shailja = no violin, dancer, vocal
Tanuja = dancer, vocal, violin (2 of them are also violin)

Q 61. Buses, Trucks, Cars (d)
Buses > Cars
Trucks < Buses
None of the given 3 options can be inferred from the passage.
Q 62. Military passage (b)
Clear from the 1st line itself.
Q 63. Alok, Bhupesh (a)
Alok + Bhupesh = Chander + Dinesh
Alok > Bhupesh
Dinesh = 2 Chander
Alok = Dinesh + 5
Clearly, Alok has highest.
Q 64. George attending classes (d)
Monday = Music
Tues = Sports
Wed = Maths
Thus = History
Friday = not Lit,
Q 65. A 11th from left (c)
10 people, A, x people, B, 9 people.
10 people, B, x people, A, 9 people. 10 + 1 + x = 17. X = 6. Total people other than A and B = 10 + 6 + 9 = 25.
Q 66. B is north of A (b)
B
A C
This is Pythagoras theorem. BC2 = AB2 + AC2 = 52 + 122 =25 + 144 = 169. So BC = 13.
Q 67. Cars meting (a)
Total distance = 160 km. Total speed = 50 + 30 = 80 km. So they will meet after 160 / 80 = 2 hours. So time of meet = 10:10 AM
Climate Change and Agriculture Passage
Q 68. (a)
Q 69 (c)
Green House Gases Passage
Q 70 (c)
Q 71 (a)
A is correct as is mentioned in the 1st para. Same para also tells us that availability of alternate resources is not a problem, specially for India. So 3 is wrong. Considering the options which have 1 but not 3, only option left is (a).
Q 72 (b)
Q 73 (d)
Both paragraphs majorly talk about how lifestyles need to be changed. This is the message of the passage.
Q 74. Nursery class (d)
Total Eng + Total Hindi – Both Eng and Hindi = 50
Total Eng = 21, Both Eng and Hindi = 10. So total Hindi = 50 + 10 – 21 = 39. Hindi only = Total Hindi – Both Hindi and Eng = 39 – 10 = 29. Similarly, only English = 21 – 10 = 11. So our ans (d)
Q 75. Area of rectangle (b)
New length = 1.4l
New width = 0.8w
New area = 1.4 * 0.8 lw = 1.12 lw. So area increases by 12%, b is correct.
Q 76. ABCDEF books (b)
A Yl New Law
B Gr New Law
C Gr Old Law
D Yl New Med
E Gr Old Med
F Gr Old Med
Q 77. 36 cm line (b)

Next 2 pts at 3, 33 cm
Next 2 pts at 6, 30 cm
Next 2 pts at 10, 26 cm
Next 2 pts at 15, 21 cm
Next pt at 15, 21 cm so not counted.
Next pt at 28, 8 cm.
Next pt at 0, 36 cm so not counted.
Thus total 12 points.
Q 78. Selling goats (c)
Let cost of 1st goat be Rs. 100. Then its selling price = 110 = selling price of goat 2. But he suffers loss of 10% on goat 2 which means cost of goat 2 = 110/.9 = 122.22
Total cost = 222.22, total selling price = 220. Means loss of ~1%.
Q 79. Guitar, violin, flute (b)
Guitar alone + flute alone + violin alone + any 2 + all 3 = 120
All 3 = 6
Any 2 = 30
