Missing Number (SSC CGL 2019 Tier -1)

1. Find the missing number? [SSC CGL 03/03/2020 (Morning)]

(a) 84
(b) 78
(c) 98
(d) 91

Correct Answer: (d) 91

Solution:Here, the pattern which is being followed column wise is:

(1st term × 3rd term) - 3rd term = 2nd term

6 × 8 = 48, 48 - 8 = 40

Thus, 14 × 7 = 98, 98 - 7 = 91

2. Find the missing number ? [SSC CGL 03/03/2020 (Afternoon)]

(a) 212
(b) 209
(c) 261
(d) 122

Correct Answer: (c) 261

Solution:Here, in the first row, Square of the 1st term + Square of the 2nd term = 3rd term. Square of 15 + Square of 6 = 225 + 36 = 261

3. Find the missing number ?

(a) 23
(b) 25
(c) 22
(d) 21

Correct Answer: (c) 22

Solution:Here, the row-wise required pattern is as follows: 1st term + 3rd term → Middle term 7 + 6 = 13, 4 + 18 = 22, 15 + 7 = 22

4. Find the missing number ?

(a) 164
(b) 166
(c) 268
(d) 162

Correct Answer: (d) 162

Solution:The required pattern is:

28 × 36 = 1008 / 4 = 252

30 × 32 = 960 / 4 = 240

36 × 18 = 648 / 4 = 162

5. Find the missing number ? [SSC CGL 04/03/2020 (Morning)]

(a) 196
(b) 200
(c) 169
(d) 199

Correct Answer: (d) 199

Solution:The required pattern is: In the 1st column, 7² + 4 = 53,

11² + 6 = 127

Similarly, 14² + 3 = 199

6. Find the missing number ?

(a) 28
(b) 29
(c) 25
(d) 27

Correct Answer: (a) 28

Solution:The logic (In Row): 1st Number = 2nd Number + 3rd Number / 2 The required pattern is:

10 = 3 + [14 / 2] → 49 = 15 + [68 / 2]

Similarly, 33 = 19 + [28 / 2]

7. Find the missing number ? [SSC CGL 04/03/2020 (Evening)]

(a) 64
(b) 96
(c) 82
(d) 74

Correct Answer: (d) 74

Solution:The pattern :+6,+10,+14, +18.... & so on starting form 4.

Thus the gap between them is 4. For eg.4= (10 - 6) & next (14 - 10)..so on

8. Find the missing number ? [SSC CGL 05/03/2020 (Morning)]

(a) 6
(b) 9
(c) 7
(d) 8

Correct Answer: (b) 9

Solution:(b) In this question, logic has been applied column wise i.e. (1st term x 3rd term)/2nd term =4th term.

So, as per 4th row = (18 x 8)/x=16 x = (18 x 8) / 16 = 9

9. Find the missing number ? [SSC CGL 05/03/2020 (Evening)]

(a) 28
(b) 24
(c) 30
(d) 14

Correct Answer: (d) 14

Solution:(d) in this question, logic has been applied column wise, i.e, (1st no.× 2nd no.) - 100

= 3rd no. 21 × 19 = 399 - 100 = 299

Similarly, 32 × 14 = 448 - 100 = 348

10. Find the missing number ? [SSC CGL 05/03/2020 (Evening)]

(a) 50
(b) 40
(c) 55
(d) 45

Correct Answer: (d) 45

Solution:(d) logic:- 42(18/3) = 252, 37(24/3) = 296

Similarly, 45(36/3) = 540
