Four of the following five are alike in a certain way and hence form a group. Which is the one that does not belong to that group?
1. BRISK: DTKUM
2. CLOUD: ENQWF
3. FLAME: HNCOG
4. GRANT: HVCRV
5. HOUSE: JQWUG
Show answer & explanation
Correct answer: C
Explanation
Use letter values (A=1, B=2 … Z=26).
BRISK → DTKUM
B(2) → D(4) = +2
R(18) → T(20) = +2
I(9) → K(11) = +2
S(19) → U(21) = +2
K(11) → M(13) = +2
Pattern: each letter +2
All pairs follow +2 letter pattern, only GRANT → HVCRV breaks this +2 pattern.
Hence, the correct answer is option 3.
