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 one out 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. PUL.
Logic: 1st letter + 5 = 2nd letter, 2nd letter - 7 = 3rd letter
Except PUL, all words follow the same logic.
