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 is the letter-cluster that DOES NOT belong to that group?
(Note: The odd man out is not based on the number of consonants/vowels or their position in the letter-cluster.)
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. ACG.
Logic: 1st letter + 3 = 2nd letter; 2nd letter + 4 = 3rd letter.
Option 1) MPT → M + 3 = P; P + 4 = T;
Option 2) ACG → A + 2 = C; C + 4 = G;
Option 3) DGK → D + 3 = G; G + 4 = K;
Option 4) HKO → H + 3 = K; K + 4 = O;
