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.)

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

Identify the Odd Letter Cluster Using Alphabetical Order

The question asks to find the letter cluster that does not fit a pattern shared by the other three, based on English alphabetical order.

Step 1: Assign Numerical Values to Letters

We assign numerical positions to each letter based on its place in the English alphabet (A=1, B=2, ..., Z=26).

  • L=12, C=3, Z=26
  • O=15, F=6, C=3
  • T=20, L=12, H=8
  • W=23, N=14, K=11

Step 2: Calculate Letter Position Differences

We calculate the difference in alphabetical position between the first and second letters of each cluster.

  • LCZ: The difference between L (12) and C (3) is \(3 - 12 = -9\).
  • OFC: The difference between O (15) and F (6) is \(6 - 15 = -9\).
  • TLH: The difference between T (20) and L (12) is \(12 - 20 = -8\).
  • WNK: The difference between W (23) and N (14) is \(14 - 23 = -9\).

Step 3: Identify the Common Pattern

Three of the letter clusters (LCZ, OFC, WNK) show a consistent pattern where the second letter is 9 positions before the first letter in the alphabet.

Step 4: Determine the Odd Letter Cluster

The letter cluster TLH is the odd one out because the difference between its first and second letters is -8 (\(12 - 20 = -8\)), which does not match the common difference of -9 found in the other three clusters.
