Question

Three of the following four letter-clusters are alike in a certain way and thus form a group. Which is the letter-cluster that does NOT belong to that group? (Note: The odd one out is not based on the number of consonants/vowels or their positions in the letter-cluster.)

The correct answer is

IKN

To solve this logical reasoning problem, we need to identify the pattern or rule that three of the letter-clusters share, which distinguishes them from the one that does not share the pattern.

  1. Let's examine the given options:
    • IKN
    • MPR
    • CFH
    • EHJ
  2. We will convert each letter to its position in the alphabet to see if a pattern emerges:
    • I (9), K (11), N (14)
    • M (13), P (16), R (18)
    • C (3), F (6), H (8)
    • E (5), H (8), J (10)
  3. Now let's look at the differences between each consecutive pair in each cluster:
    • For IKN: K - I = 11 - 9 = 2, N - K = 14 - 11 = 3
    • For MPR: P - M = 16 - 13 = 3, R - P = 18 - 16 = 2
    • For CFH: F - C = 6 - 3 = 3, H - F = 8 - 6 = 2
    • For EHJ: H - E = 8 - 5 = 3, J - H = 10 - 8 = 2
  4. From this, we can see:
    • The pattern or rule shared by MPR, CFH, and EHJ is that the differences between the letters are in the order of 3 and 2.
    • IKN differs from the rest since its pairwise differences are 2 and 3, not following the same 3 and 2 pattern as the other clusters.
  5. Conclusion: The letter-cluster that does not belong to the group based on the identified pattern is IKN.
