- A.
ABDV
- B.
LJMQ
- C.
XFHL
- D.
GCEI
Attempted by 40 students.
Show answer & explanation
Correct answer: A
Key insight: convert each letter to its position in the alphabet and add the positions. A group whose total is odd is the odd one out because the other groups total to even numbers.
ABDV: A=1, B=2, D=4, V=22 → 1 + 2 + 4 + 22 = 29 (odd).
LJMQ: L=12, J=10, M=13, Q=17 → 12 + 10 + 13 + 17 = 52 (even).
XFHL: X=24, F=6, H=8, L=12 → 24 + 6 + 8 + 12 = 50 (even).
GCEI: G=7, C=3, E=5, I=9 → 7 + 3 + 5 + 9 = 24 (even).
Conclusion: ABDV is the odd group because its letter-position sum is odd while the sums for the other groups are even.
