Three of the following letter-clusters are alike in some manner and one is different. Select the one that is different.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. PKQJ.
The logic used here is: 1st letter + 2 = 2nd letter, 2nd letter - 1 = 3rd letter, 3rd letter + 2 = 4th letter
Option 1: PKQJ = P + 2 = R, K - 1 = J, Q + 2 = S: This does not follow the logic.
