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 letter-cluster 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.)

• A. PR - UW
• B. DF - HJ
• C. HJ - LN
• D. LN - PR

Answer 1

Answer:

A. PR - UW

The letter-cluster pair that DOES NOT belong to the group is PR - UW.

The Pattern

For all other pairs, the relationship between the first cluster and the second cluster follows a consistent pattern of skipping one letter for each corresponding position:

• DF - HJ: D (+4) → H, and F (+4) → J

• HJ - LN: H (+4) → L, and J (+4) → N

• LN - PR: L (+4) → P, and N (+4) → R

Why PR - UW is the Odd One Out

Applying the same logic to PR:

• P (+5) → U

• R (+5) → W

Because this pair adds 5 to its letters instead of 4, it breaks the group's rule.
