SSC CHSL - 15th October 2020 - Shift 3 • Reasoning • Q81

Select the option in which the numbers are related in the same way as are the numbers in the given set.

(4, 67, 20)

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e (3, 30, 12).

Understanding Application

The logic used here is: 

(1st no)3 + 3 = 2nd no

(1st no) x (1st no + 1) = 3rd no

(4, 67, 20)

43 + 3 = 67

4 x 5 = 20

Similarly,

(3, 30, 12)

33 + 3 = 30

3 x 4 = 12

Hence, option 2 is the correct answer.
