Answers :
1) Answer: B
4 * 2 + 2 = 10
10 * 3 + 3 = 33
33 * 4 + 4 = 136
136 * 5 + 5 = 685
685 * 6 + 6 = 4116
2) Answer: A
1944/2 – 4 = 968
968/2 – 4 = 480
480/2 – 4 = 236
236/2 – 4 = 114
114/2 – 4 = 53
3) Answer: D
4) Answer: C
88 + 77 = 165
165 + 55 = 220
220 + 33 = 253
253 + 11 = 264
5) Answer: D
85 + 52 = 110
110 – 42 = 94
94 + 32 = 103
103 – 22 = 99
99 + 12 = 100
Directions (6-10) :
6) Answer: D
From Quantity I,
Area of the rectangle = 216
3x * 2x = 216
x2 = 36
x = 6 cm
Perimeter of the rectangle = 2 * (3 * 6 + 2 * 6) = 60 cm
From Quantity II,
63 cm
Quantity I < Quantity II
7) Answer: C
From Quantity II,
CI = P (1 + R/100)2 – P
CI = 1800 * (1 + 10/100)2 – 1800
= 378
From Quantity II,
Difference = 37800 * 10 * 10/(100 * 100)
= 378
Quantity I = Quantity II
8) Answer: D
From Quantity I,
18 seconds
From Quantity II,
Required time = 180/(20 * 5/18) = 32.4 seconds.
Quantity I < Quantity II
9) Answer: A
From Quantity I,
(4x + 8)/(5x + 8) = 5/6
25x + 40 = 24x + 48
x = 8 years
A = 4 * 8 = 32 years
B = 5 * 8 = 40 years
After 15 years A and B’s age is 47 and 55 years respectively.
Difference between the ages of A and B = 8 years
From Quantity II,
6 years
Quantity I > Quantity II
10) Answer: D
From Quantity I,
A = 1/10
B = 1/18
C = 18 * 100/150 = 12 days
A + B + C = 1/10 + 1/18 + 1/12
= (18 + 10 + 15)/180
= 43/180
Required time = 180/43 days
From Quantity II,
5 days
Quantity I < Quantity II
