SSC CHSL 2020 PYQ — Question 95

SSC CHSL - 17th October 2020 - Shift 1 • Reasoning • Q95

Select the option that does NOT belong to the given series:

EC, H, HF, N, KI, U

Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e U.

 Understanding 

The logic used here is;

EC, H, HF, N, KI, U

E + C = 5 + 3 = 8 = H

H + F = 8 + 6 = 14 = N

K + I = 11 + 9 = 20 = T

The series should be:

EC, H, HF, N, KI, T

Hence, U does not belong to the series.

Hence, option 4 is the correct answer.
