Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster does not belong to that group?
(Note: The odd letter-cluster is not based on the number of consonants/vowels or their position in the letter-cluster.)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. KON.
Option 1: CGE - C + 4 = G; G - 2 = E
Option 2: MQO - M + 4 = Q; Q - 2 = O
Option 3: GKI - G + 4 = K; K - 2 = I
Option 4: KON - K + 4 = O; O - 2 = M (not equal to N)
All are follow the same logic except option 4.
