Answers:
Directions (1-5):
Answer: a)
3.5*1 + 1 = 4.5
4.5*2 + 2 = 11
11*3 + 3 = 36
36*4 + 4 = 148
148*5 + 5 = 745
Answer: d)
16*(1/2) = 8
8*(3/2) = 12
12*(5/2) = 30
30*(7/2) = 105
105*(9/2) = 472.5
Answer: b)
78 – 22 = 56
56 + 28 = 84
84 – 22 = 62
62 + 28 = 90
90 – 22 = 68
(Or)
The alternative difference is, + 6
Answer: c)
1156 + (1*3) = 1159
1159 + (2*6) = 1171
1171 + (3*9) = 1198
1198 + (4*12) = 1246
1246 + (5*15) = 1321
(Or)
The difference of difference is, 6, 6, 6,…
5) Answer: a)
224*0.5 + 13 = 113
113*1 + 23 = 121
121*2 + 33 = 269
269*4 +43 = 1140
1140*8 + 53 = 9245
Directions (6-10):
6) Answer: c)
Total number of female professors in university A
= > 1200*(5/12) = 500
Total number of female associate professors in university A
= > 500*(2/5) = 200
The total number of female assistant professors in university A
= >500 – 200 = 300
7) Answer: b)
The average of difference between the assistant professors to that of associate professors of all the given subjects except the economics in university A
= > (141 + 100 + 63 + 138 + 89) –(75 + 80 + 105 + 90 + 55)
= > (531 – 405) = 126
8) Answer: d)
The total number of associate professors teaching the subjects of Maths, Economics and Hindi together
= >500*(55/100) = 275
The total assistant professors teaching the subjects of Computer science and History together
= >[1200*(15/100) – 500*(16/100)] + [1200*(19/100) – 500*(18/100)]
= > [180 – 80] + [228 – 90]
= > 100 + 138 = 238
Required ratio = 275 : 238
9) Answer: a)
Total number of professors teaching the subjects of Hindi and Physics together
= >1200*(26/100) = 312
Total number of associate professors teaching the subjects of Computer science and History together
= >500*(34/100) = 170
Required % = (312/170)*100 = 183.52 % = 185 %
10) Answer: c)
The total number of professors teaching the subjects of Maths and Economics together
= >1200*(40/100) = 480
The total number of assistant professors teaching the subjects of Economics and Physics together
= >[1200*(22/100) – 500*(19/100)] + [1200*(12/100) – 500*(11/100)]
= > [264 – 95] + [144 – 55]
= > 169 + 89 = 258
Required difference = 480 – 258 = 222
