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?

1. A

   MNT

2. B

   RSY

3. C

   FGM

4. D

   TUP

Appeared in: DSSSB 6 September 2024

Explanation

• The question requires identifying the letter cluster that does not follow the pattern shared by the other three.
• The common pattern is based on the alphabetical positions of the letters: the second letter is 1 position after the first, and the third letter is 6 positions after the second (+1, +6).
• The cluster TUP follows a different pattern: the second letter is 1 position after the first (T+1=U), but the third letter is 5 positions before the second (U-5=P).
• This deviation from the (+1, +6) rule makes TUP the odd one out.

Why Other Options Were Wrong

• Option A: The letter cluster MNT follows the common pattern. The position of N is M+1, and the position of T is N+6.
• Option B: The letter cluster RSY follows the common pattern. The position of S is R+1, and the position of Y is S+6.
• Option C: The letter cluster FGM follows the common pattern. The position of G is F+1, and the position of M is G+6.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Identifying patterns in letter clusters (Odd One Out) as background academic context rather than a clinical decision trigger.
• While not a clinical question, this type of problem assesses logical reasoning and pattern recognition, which are foundational skills for critical thinking in nursing.
• Nurses constantly use pattern recognition to identify subtle changes in a patient's condition, interpret trends in vital signs or lab results, and make timely clinical decisions.
• Strong analytical skills help in prioritizing care, troubleshooting equipment, and applying the nursing process effectively.

How to Approach the Question

• First, understand the goal: find the one letter group that has a different pattern from the other three.
• Assign numerical positions to the letters in each option (A=1, B=2, C=3, etc.).
• For the first option (MNT), calculate the difference in position between the letters: M(13) to N(14) is +1, and N(14) to T(20) is +6. The pattern is (+1, +6).
• Systematically test this (+1, +6) pattern against the remaining options (RSY, FGM, TUP).
• Identify the option that does not conform to this pattern.
• The cluster TUP shows a pattern of (+1, -5), which is different from the others, making it the correct answer.

Concept Tested & Keywords

• Concept Tested: Logical Reasoning: Identifying patterns in letter clusters (Odd One Out).
• Stem keywords: letter clusters, alike, does not belong, group
• Lead-in keywords: does not belong
• Negative lead-in flag: NOT changes the reasoning strategy; look for the exception or incorrect statement rather than the true statement.
