Out of the given options, three are similar in a certain manner. However, one option is NOT like the other three. Select the option which is different from the rest?

1. A

   WTQ

2. B

   LIF

3. C

   ZWS

4. D

   PMJ

Appeared in: DSSSB - 29 August 2019 (Shift-2)

Explanation

• The correct option is ZWS because it follows a different numerical pattern compared to the other options.
• When converting the letters to their alphabetical positions (Z=26, W=23, S=19), the pattern of differences is -3, -4.
• This is inconsistent with the other three options, which all share a uniform pattern of -3, -3.

Why Other Options Were Wrong

• Option A: The option WTQ follows the common pattern. The alphabetical positions are 23, 20, and 17, with a consistent difference of -3 between each letter.
• Option B: The option LIF follows the common pattern. The alphabetical positions are 12, 9, and 6, with a consistent difference of -3 between each letter.
• Option D: The option PMJ follows the common pattern. The alphabetical positions are 16, 13, and 10, with a consistent difference of -3 between each letter.

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 (Letter Series) as background academic context rather than a clinical decision trigger.
• This question type assesses logical reasoning and pattern recognition, which are fundamental cognitive skills.
• While not directly clinical, these skills are crucial for nurses in problem-solving, interpreting data, and making sound clinical judgments under pressure.
• What if the pattern was based on vowels or consonants? The approach would change from numerical analysis to identifying the properties of the letters themselves.

How to Approach the Question

• First, read the question carefully to understand the task: find the option that is different from the others.
• Recognize that this is a letter series problem. The most common approach is to analyze the numerical positions of the letters in the alphabet.
• Convert the letters in each option to their corresponding numerical values (A=1, B=2, etc.).
• Calculate the difference (or 'gap') between consecutive numbers in each option's sequence.
• Compare the patterns of differences across all four options.
• The option with a unique or inconsistent pattern is the correct answer.

Concept Tested & Keywords
