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: C
Explanation
The correct answer is option 3 i.e. JQM
Logic: 1st letter + 7 = 2nd letter, 2nd - 3 = 3rd letter
Option 1: OVS ⇒ O + 7 = V, V - 3 = S
Option 2: LSP ⇒ L + 7 = S, S - 3 = P
Option 4: NUR ⇒ N + 7 = U, U - 3 = R
Option 3: JQM ⇒ J + 7 = Q, Q - 3 = N ≠ M
All follow the same logic except option 3.
