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: B
Explanation
The correct answer is option 2 i.e. QUS.
Logic: 1st letter + 1 = 3rd letter; 3rd letter + 3 = 2nd letter.
Except QUS, All words follow the same pattern. while in QUS Q + 1 = R (not S), S + 3 = V (not U).
