Show answer & explanation
Correct answer: B
Concept: In a letter-group classification (odd-one-out) question, convert every letter to its position in the alphabet (A=1 ... Z=26) and test whether the SAME arithmetic rule links all three letters in three of the four groups - the group that breaks that shared rule is the odd one out.
Group | 1st letter + 2 | Result - 1 | Actual 3rd letter | Follows rule? |
|---|---|---|---|---|
KML | K(11)+2 = M(13) | M(13)-1 = L(12) | L | Yes |
PRQ | P(16)+2 = R(18) | R(18)-1 = Q(17) | Q | Yes |
TVU | T(20)+2 = V(22) | V(22)-1 = U(21) | U | Yes |
NPQ | N(14)+2 = P(16) | P(16)-1 = O(15) | Q | No (should be O, not Q) |
Cross-check: KML, PRQ, and TVU each satisfy first-letter+2 = second letter and second-letter-1 = third letter. NPQ is the only group whose third letter does not match what the rule predicts, so it is the exception.
Result: NPQ is the odd one out.
