a. 282
b. 121
c. 166
d. 220
e. 352

B. 121

192– 9 = 352
172– 7 = 282
152– 5 = 220
132– 3 = 166
112– 1 = 120
so, 120 should be in place of 121

2. 1/3, 1/2, 3/5, 2/3, 5/8, 3/4
a. 1/2
b. 2/3
c. 3/5
d. 5/8
e. 3/4

D. 5/8

The series is
(1 * 2)/(2 * 3) = 1/3,
(2 * 3)/(3 * 4) = 1/2,
(3 * 4)/(4 * 5) = 3/5
(4 * 5)/(5 * 6) = 2/3,
(5 * 6)/(6 * 7) = 5/7,
(6 * 7)/(7 * 8) = 3/4
so, 5/7 should be in place of 5/8

3. What would come in place of the question mark (?) in the following number series?
112, 125, 161, 165, ?
a. 190
b. 125
c. 195
d. 201
e. 175

D. 201

First and last digit is added and their square is added in the number.
112 + (1 + 2)2= 121
121 + (1 + 1)2= 125
125 + (1 + 5)2= 161
161 + (1 + 1)2= 165
165 + (1+5)2= 201

4. What would come in place of the question mark (?) in the following number series?
103, 107, 109, 113, 127,?, 137
a. 133

b. 129.6
c. 136.6
d. 144
e. 132.4

B. 129.6

The next number is multiplied by 1.2 that is,
75 × 1.2 = 90
90 × 1.2 = 108
108 × 1.2 = 129.6
129.6 × 1.2 = 155.52
155.52 × 1.2 = 186.624

6. The following numbers form a series. Find the odd one out.
400, 399, 391, 364, 300, 225
a. 225
b. 391
c. 364
d. 300
e. None of these

A. 225

The series follows the pattern:
400 – 13= 399, 399 – 23= 391, 391 – 33= 364, 364 – 43= 300, 300 – 53= 175
Therefore, 175 should be in place of 225.

7. The following numbers form a series. Find the odd one out.
250, 259, 277, 304, 340, 396
a. 396
b. 340

Therefore, 385 should be in place of 396.

Therefore, 2100 should be in place of 4400.

9.  The following numbers form a series. Find the odd one out.
