Question

Based on the English alphabetical order, three of the following four letter-clusters are alike in a certain way and thus form a group. Which letter-cluster 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. RIZ
• B. EVM
• C. ARI
• D. WNI

Answer 1

Answer:

D. WNI

The letter-cluster that DOES NOT belong to the group is WNI.

Explanation:

This pattern is based on opposite letters in the English alphabet (pairs that add up to 27 in position value, such as A-Z, B-Y, etc.):

• RIZ: R and I are opposites. (Z is left over).

• EVM: E and V are opposites. (M is left over).

• ARI: A and R are not opposites, but R and I are opposites. It contains an opposite pair.

• WNI: W, N, and I do not contain any opposite letter pairs (W pairs with D, N pairs with M, and I pairs with R).

Alternatively, looking closely at the specific structure of the first three pairs:

• R $\leftrightarrow$ I (Opposite pair) + Z

• E $\leftrightarrow$ V (Opposite pair) + M

• A + R $\leftrightarrow$ I (Opposite pair)

Every group contains exactly one pair of alphabet opposites except WNI.
