SSC CHSL - 15 April 2021 - Shift 1 • Reasoning • Q90

Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the letter cluster that is different.

Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option  2 i.e. PBGF.

 Understanding 

The logic used here is:

Add all the positional values of the letters.

1. LKHZ → 12 + 11 + 8 + 26 = 57

2.PBGF → 16 + 2 + 7 + 6 = 31

3. HJDT → 8 + 10 + 4 + 20 = 42

4. MNBS → 13 + 14 + 2 + 19 = 48

As we can see that 57, 42, and 48 all are multiple of 3, but 31 is not a multiple of 3.

Hence, PBGF is the odd one out.
