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.)

This question was previously asked in
RRB ALP 2025 CBT 2 Wiremen Question Paper (28-Jul-2026) (Shift 2)
The correct answer is
NR−OV

Letter Pair Analogy Reasoning

The question asks to identify the letter-cluster pair that does not follow the pattern established by the others. The pattern involves the relationship between letters based on their position in the English alphabet.

Analyzing Alphabetical Positions

First, let's determine the numerical position of each letter in the alphabet:

  • A=1, B=2, ..., H=8, J=10, L=12, M=13, N=14, O=15, Q=17, R=18, S=19, T=20, V=22, X=24, Z=26

Pattern Identification

We examine the relationship within each pair and between the pairs for the options that seem similar:

  • Option 1: HL−JN
    • H (8) and L (12): The difference is \(12 - 8 = 4\).
    • J (10) and N (14): The difference is \(14 - 10 = 4\).
    • Relationship between pairs: H to J is \(10 - 8 = +2\). L to N is \(14 - 12 = +2\).
    • Pattern: (X, X+4) followed by (X+2, X+4+2).
  • Option 3: MQ−OS
    • M (13) and Q (17): The difference is \(17 - 13 = 4\).
    • O (15) and S (19): The difference is \(19 - 15 = 4\).
    • Relationship between pairs: M to O is \(15 - 13 = +2\). Q to S is \(19 - 17 = +2\).
    • Pattern: (X, X+4) followed by (X+2, X+4+2).
  • Option 4: TX−VZ
    • T (20) and X (24): The difference is \(24 - 20 = 4\).
    • V (22) and Z (26): The difference is \(26 - 22 = 4\).
    • Relationship between pairs: T to V is \(22 - 20 = +2\). X to Z is \(26 - 24 = +2\).
    • Pattern: (X, X+4) followed by (X+2, X+4+2).

Analyzing the Odd Pair Out

Now, let's analyze Option 2 (NR−OV) using the same criteria:

  • Option 2: NR−OV
    • N (14) and R (18): The difference is \(18 - 14 = 4\). (This part matches the pattern).
    • O (15) and V (22): The difference is \(22 - 15 = 7\). (This part deviates; the difference is not 4).
    • Relationship between pairs: N to O is \(15 - 14 = +1\). R to V is \(22 - 18 = +4\). (These deviations also do not match the +2 pattern).

Conclusion

Options 1, 3, and 4 share a consistent pattern: each pair has letters separated by 4 positions, and the second pair's letters are 2 positions after the first pair's corresponding letters. Option 2 (NR−OV) breaks this pattern because the second pair (OV) has letters separated by 7 positions, not 4, and the progression between pairs is not +2.

Therefore, the letter-cluster pair that does not belong to the group is NR−OV.
