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. RVS
• B. OSP
• C. YUV
• D. LPM

Answer 1

Answer:

C. YUV

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

The Logic Explained

Let's analyze the alphabetical positions (A = 1, B = 2, ..., Z = 26) for each letter in the clusters:

• RVS:

  • R (18) $\rightarrow$ V (22): +4

  • V (22) $\rightarrow$ S (19): -3

• OSP:

  • O (15) $\rightarrow$ S (19): +4

  • S (19) $\rightarrow$ P (16): -3

• LPM:

  • L (12) $\rightarrow$ P (16): +4

  • P (16) $\rightarrow$ M (13): -3

As you can see, RVS, OSP, and LPM all follow a consistent pattern of (+4, -3).

Now let's check YUV:

• Y (25) $\rightarrow$ U (21): -4

• U (21) $\rightarrow$ V (22): +1

Because YUV breaks the established (+4, -3) pattern of the group, it is the odd one out.
