Four letter-clusters have been given, out of which three are alike in some manner and one is different. Select the odd letter-cluster.
Answer & explanation
Correct answer: option 2
THE LOGIC;
1) KMOQS,
K → (+2) → M → (+2) → O → (+2) → Q → (+2) → S
2) SQOMK,
S → (-2) → Q → (+2) → O → (+2) → M → (+2) → K
3) FHJLN,
F → (+2) → H → (+2) → J → (+2) → L → (+2) → N
4) PRTVX,
P → (+2) → R → (+2) → T → (+2) → V → (+2) → X
Thus, SQOMK is the odd one.
