Question

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.)

The correct answer is Option D: MS - LH. Convert each letter in both letter-clusters to its alphabetical position (A=1 to Z=26) and check the sum or difference pattern between the first cluster and the second cluster.

Step-by-Step Solution & Concepts:
Shortcut Trick: Convert each letter in both letter-clusters to its alphabetical position (A=1 to Z=26) and check the sum or difference pattern between the first cluster and the second cluster.

Steps: Analyze Option A (QL - OJ): Q (17) -> O (15) is -2. L (12) -> J (10) is -2. Pattern is -2, -2.. Analyze Option B (WR - UP): W (23) -> U (21) is -2. R (18) -> P (16) is -2. Pattern is -2, -2.. Analyze Option C (ID - GB): I (9) -> G (7) is -2. D (4) -> B (2) is -2. Pattern is -2, -2.. Analyze Option D (MS - LH): M (13) -> L (12) is -1. S (19) -> H (8) is -11. This breaks the uniform -2, -2 pattern.

Answer: D is correct because MS - LH does not follow the uniform minus 2 position shift pattern seen in the other three pairs.

Why options are wrong: A: QL-OJ follows -2, -2 letter shift rule. B: WR-UP follows -2, -2 letter shift rule. C: ID-GB follows -2, -2 letter shift rule. D is incorrect as it deviates from the uniform -2 decrement pattern.

Exam Tip: When letter clusters do not match standard vowel-consonant rules, immediately write down the alphabetical number positions (1 to 26) to find arithmetic differences.
