Three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which is the letter-cluster pair that does NOT belong to that group?
(Note: The odd one out is not based on the number of consonants/vowels or their positions in the letter-cluster.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. PF - OI
Logic: The difference between the letters is 10.
EJ - OT: E + 10 = O, J + 10 = T
PF - OI: P + 10 = Z, F + 10 = P
KP - UZ: K + 10 = U, P + 10 = Z
CH - MR: C + 10 = M, H + 10 = R
