Three of the following four letter-clusters are alike in a certain way and one is different. Pick the odd one out.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. PSQR.
The logic used here is:
1st letter + 1 = 3rd letter
2nd letter + 1 = 4th letter
Option 1: PSQR
P + 1 = Q
S - 1 = R
This does not follow the logic.
Hence, option 1 is the odd one out.
