Three of the following four letter-cluster pairs are alike in a certain way and so form a group. Which one of the following does not belong to that group? (The relationship is not based on number of consonants/vowels or their position in the alphabet-cluster.)

1. A

   JH-LF

2. B

   DB-FC

3. C

   LJ-NK

4. D

   HF-JG

Appeared in: DSSSB 12 August 2024

Explanation

• This pair is the correct answer because it follows a unique pattern compared to the others.
• The relationship between the letters is J (+2 positions) → L, and H (-2 positions) → F.
• This (+2, -2) pattern is different from the (+2, +1) pattern observed in the other three options, making it the odd one out.

Why Other Options Were Wrong

• Option B: This option is incorrect because it follows the common pattern shared by two other options.
• Option C: This option is incorrect because it adheres to the group's common pattern.
• Option D: This option is incorrect as it also follows the established pattern of the group.

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 alphabetical series to find the odd one out as background academic context rather than a clinical decision trigger.
• While not a clinical question, this type of logical reasoning tests pattern recognition, analytical thinking, and attention to detail.
• These cognitive skills are essential for nurses in clinical practice for tasks such as interpreting lab data trends, recognizing subtle changes in a patient's condition, and making rapid, accurate decisions.
• What if? If the question asked for a pair that follows a (-2, -1) pattern, none of the current options would be correct, and a new search for that specific pattern would be needed.

How to Approach the Question

• First, understand the task: find the letter-cluster pair that has a different relationship pattern compared to the others.
• Analyze the relationship between the first letters of the first cluster and the second cluster in each option (e.g., J to L, D to F).
• Next, analyze the relationship between the second letters of the first and second clusters in each option (e.g., H to F, B to C).
• To make the pattern clear, convert the letters to their numerical positions in the alphabet (A=1, B=2, etc.) and calculate the difference.
• Identify the common pattern that emerges in three of the options. In this case, it is (+2, +1).
• The option that does not follow this common pattern is the correct answer.
