Three of the following four letter-cluster pairs are alike in a certain way and thus form a group. Which is the letter-cluster pair that does not belong to that group?

1. A

   QVJ

2. B

   RWK

3. C

   SXL

4. D

   PUO

Appeared in: DSSSB 6 September 2024

Explanation

• The pattern involves the alphabetical position of the letters.
• The rule is: First Letter's Position + 5 = Second Letter's Position; Second Letter's Position - 12 = Third Letter's Position.
• In the cluster PUO, the logic is P(16) + 5 = U(21), which is correct.
• However, the second step is U(21) - 6 = O(15), which violates the '-12' rule followed by the other three groups.

Why Other Options Were Wrong

• Option A: This option correctly follows the established pattern.
• Option B: This option correctly follows the established pattern.
• Option C: This option correctly follows the established pattern.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning: Odd One Out as background academic context rather than a clinical decision trigger.
• This question type is not directly related to clinical nursing practice.
• It assesses logical reasoning and pattern recognition, which are foundational cognitive skills for problem-solving and critical thinking in any professional field, including nursing.
• For example, a nurse uses pattern recognition to identify subtle changes in a patient's vital signs or symptoms that may indicate a deteriorating condition.

How to Approach the Question

• First, analyze the question to understand the task: find the letter cluster that does not fit the pattern of the others.
• Assign a numerical value to each letter in the clusters based on its position in the alphabet (A=1, B=2, C=3, etc.).
• Examine the first letter cluster (QVJ) to find a potential mathematical relationship between the numbers (e.g., 17, 22, 10). The pattern is +5, -12.
• Test this hypothesis (+5, -12) on the subsequent letter clusters (RWK and SXL).
• Identify the cluster (PUO) where the pattern does not hold true.
• Confirm that this cluster is the only one that deviates, making it the correct answer.

Concept Tested & Keywords

• Concept Tested: Logical Reasoning: Odd One Out
• Stem keywords: letter-cluster pairs, alike, does not belong, group
• Lead-in keywords: Which is the letter-cluster pair that does not belong to that group?
• Negative lead-in flag: NOT changes the reasoning strategy; look for the exception or incorrect statement rather than the true statement.
