SSC CGL - 17 Aug 2021 - Shift 3 • Reasoning • Q77

Select the option in which the numbrs are NOT related in the same way as are the numbers of the following set.

(7, 51, 22)

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e (6, 38, 22).

Given Number : ( 7, 51, 22 )

Logic:

(1st number)2 + 2 = 2nd number

1st number + 15 = 3rd number

72 + 2 = 49 + 2 = 51(2nd number)

7 + 15 = 22 (3rd number)

Let's use this logic in all the options: 

1) ( 4, 18, 19 )

      42 + 2 = 16 + 2 = 18

      4 + 15 = 19

2) ( 11, 123, 26 )

      112 + 2 = 121 + 2 = 123

      11 + 15 = 26

3) ( 6, 38, 22 )

      62 + 2 = 36 + 2 = 38

      6 + 15 = 21

4) ( 3, 11, 18 )

      32 + 2 = 11

      3 + 15 = 18

All the options follow the logic except option 3. Hence, Option 3 is the correct answer.
