Based on the English alphabetical order, three of the following four letter cluster pairs are alike in a certain way and thus form a group. Which pair does NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their position in the letter cluster)
LH - QM
KF - MH
QL - SN
EZ - GB
LH - QM
Convert each letter in the pairs to its alphabetical position and find the pattern between the first pair and second pair.
Convert each letter in the pairs to its alphabetical position and find the pattern between the first pair and second pair.
Analyze Pair A (LH - QM)
L is 12 and Q is 17 (difference of +5). H is 8 and M is 13 (difference of +5). Both follow a +5 shift.
Analyze Pair B (KF - MH)
K is 11 and M is 13 (difference of +2). F is 6 and H is 8 (difference of +2). Both follow a +2 shift.
Analyze Pair C (QL - SN)
Q is 17 and S is 19 (difference of +2). L is 12 and N is 14 (difference of +2). Both follow a +2 shift.
Analyze Pair D (EZ - GB)
E is 5 and G is 7 (difference of +2). Z is 26 and B is 2 (difference of +2 cyclically). Both follow a +2 shift.
B: Follows +2 shift. C: Follows +2 shift. D: Follows +2 shift.
A is correct because LH - QM follows a +5 alphabetical shift rule, whereas the other three pairs follow a +2 alphabetical shift rule.
When analyzing letter pairs, always find the numerical position difference between the first and second letter cluster first before checking cross-letter relationships.
