SSC CPO Tier I - 12th December 2019 - Shift 2 • Reasoning • Q182

Three of the four options are similar to the given number set in a certain manner while one is different. Select the option that is NOT like the given number set.
(90, 450, 810)

Show answer & explanation

Correct answer: C

Explanation

The correct answer is Option 3 i.e. (7, 35, 56).

Understanding

Here, the pattern is

90 x 5 = 450

90 x 9 = 810

Options A, B, D follows the same pattern.

A) (5, 25, 45) = 5 x 5 = 25, 5 x 9 = 45.

B) (21, 105, 189) = 21 x 5 = 105, 21 x 9 = 189.

D) (17, 85, 153) = 17 x 5 = 85, 17 x 9 = 153.

But option C (7, 35, 56) does not follow the pattern.

Hence, the correct answer is option 3.
