SSC CGL - 20 Aug 2021 - Shift 2 • Reasoning • Q93

Select the option that is related to the fourth number in the same way as the first number is related to the second number and the fifth number is related to the sixth number.

8: 24 :: ?: 52 :: 18: 114

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 12.

The logic used here is:

8: 24

[8 × (8 + 1)] ÷ 3 = [8 × 9] ÷ 3 = 72 ÷ 3 = 24

18: 114

[18 × (18 + 1)] ÷ 3 = [18 × 19] ÷ 3 = 342 ÷ 3 = 114

Similarly,

?: 52

[a × (a + 1)] ÷ 3 = 52

a = 12

Hence, option 1 is the correct answer.
