Based on 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 or positions of consonants and vowels in the cluster.)
Answer: B. LPR — ConceptIn alphabet-pattern questions, replace each letter by its position: A = 1, B = 2, ..., Z = 26. For a three-letter cluster with positions p, q, r,…
- A.

- B.

- C.
BEH
- D.
KNQ

Correct answer: B
Concept
In alphabet-pattern questions, replace each letter by its position: A = 1, B = 2, ..., Z = 26. For a three-letter cluster with positions p, q, r, compute the consecutive gaps q − p and r − q.
Clusters belong to the same pattern when their ordered pair of gaps is the same; the starting letter itself need not be the same.
Application
ORU maps to 15, 18, 21, so its gaps are +3 and +3.
LPR maps to 12, 16, 18, so its gaps are +4 and +2.
BEH maps to 2, 5, 8, so its gaps are +3 and +3.
KNQ maps to 11, 14, 17, so its gaps are +3 and +3.
ORU, BEH, and KNQ share the ordered gap pair (+3, +3), whereas LPR has the pair (+4, +2). Therefore, LPR does not belong to the group.
Cross-check
Moving three alphabet positions twice gives O → R → U, B → E → H, and K → N → Q. Starting from L, the same rule would give L → O → R, not L → P → R. This independently confirms LPR as the odd cluster.
Result: LPR is the letter cluster that does not belong to the group.
