SSC CHSL - 12th October 2020 - Shift 2 • Reasoning • Q87

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

(9, 217, 8)

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e (4, 37, 3)

Understanding Application

(a, b, c) 

→ (a + c)2 - (a x c) = b

(9, 217, 8)

→ (9 + 8)2 - (9 x 8)

= 289 - 72

= 217

A similar relation can be seen in option 1,

(4, 37, 3)

→ (4 + 3)2 - (4 x 3) 

= 49 - 12

= 37

Hence, the correct answer is (4, 37, 3)

As we get our answer from option 1, we dont need to check futher options.
