Four letter clusters have been given, out of which three are alike in some manner and one is different. Select the odd letter cluster.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. NJPM.
The logic used here is: 1st letter - 4 = 2nd letter, 2nd letter + 5 = 3rd letter, 3rd letter - 2 = 4th letter
Option 1: NJPM: N - 4 = J, J + 5 = O, O - 2 = M: This does not follow the logic.
