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 one out is not based on the number of consonants/vowels or their position in the letter-cluster.)
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. CHE.
Logic: 1st letter + 3 = 3rd letter; 2nd letter - 3 = 3rd letter
Except CHE, All words follow the same pattern while CHE → C + 3 = F (not E); H - 3 = E.
