Missing Number (SSC CGL 2019 Tier -1)

Total Questions: 16

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

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

21 × 25 = 525 - 25 = 500

Thus, 14 × 7 = 98, 98 - 7 = 91

Hence, "91" is the correct answer

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

Correct Answer: (c) 261
Solution:Here, in the first row, Square of the 1st term + Square of the 2nd term = 3rd term.

Square of 5 + Square of 4 = 25 + 16 = 41

Square of 9 + Square of 11 = 81 + 121 = 202

Square of 15 + Square of 6 = 225 + 36 = 261

Hence, "261" is the correct answer

3. Find the missing number ?

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

Hence, "22" is the correct answer

4. Find the missing number ?

Correct Answer: (d) 162
Solution:The required pattern is:

First row term × Second row term = Total number/4 = Third row term

28 × 36 = 1008 / 4 = 252

30 × 32 = 960 / 4 = 240

36 × 18 = 648 / 4 = 162

Hence, "162" is the correct answer

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

Correct Answer: (d) 199
Solution:The required pattern is:

(First row term)²+Third row term = Second row term

7² + 4 = 53,

11² + 6 = 127

Similarly, 14² + 3 = 199

Hence, "199" is the correct answer

6. Find the missing number ?

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]

Hence, "28" is the correct answer

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

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

Hence, "74" is the correct answer

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

Correct Answer: (b) 9
Solution: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

Hence, "9" is the correct answer

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

Correct Answer: (d) 14
Solution:In this question, logic has been applied column-wise, i.e,

(1st no.× 2nd no.) - 100= 3rd no.

21 × 19 = 399 - 100 = 299

18 × 22 = 396 -100 = 296

Similarly, 32 × 14 = 448 - 100 = 348

Hence, "14" is the correct answer

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

Correct Answer: (d) 45
Solution:The pattern followed here is :

(First number )*(Second number/3) = (Third number)

logic: - 42(18/3) = 252,

37(24/3) = 296

Similarly, 45(36/3) = 540

Hence, "45" is the correct answer.
