Explanation

Listen in Hindi

• The question is a logical reasoning puzzle about a circular seating arrangement.
• The key statement is: 'R is sitting immediately to the right of Q'.
• In a circular setup, if person A is to the immediate right of person B, then person B is, by definition, to the immediate left of person A.
• Applying this rule, since R is to the right of Q, it logically means Q must be to the immediate left of R.
• The second clue ('T is sitting between P and S') is extra information not needed to solve for the person to the left of R.

Why Other Options Were Wrong

• Option A: P's position is next to T. Depending on the final arrangement, P could be next to R on the other side, but not on the immediate left.
• Option C: The problem explicitly states that 'T is sitting between P and S'. This means T cannot be sitting next to R.
• Option D: S's position is next to T. Similar to P, S might be adjacent to R on the right side in one of the possible configurations, but not on the immediate left.

Clinical Relevance

• Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Logical Reasoning - Circular Seating Arrangement as background academic context rather than a clinical decision trigger.
• Logical reasoning is a fundamental skill for nurses, essential for critical thinking and clinical decision-making.
• This type of problem-solving mirrors the process of interpreting patient data, where a nurse must connect different pieces of information (like vital signs, lab results, and symptoms) to reach a logical conclusion about patient status.
• The ability to make quick, accurate deductions from given information is crucial for prioritizing care and responding effectively in fast-paced healthcare environments.

How to Approach the Question

• Identify the question type: This is a logical reasoning problem involving a circular seating arrangement.
• Break down the provided information into distinct, manageable clues. Clue 1: 'R is to the immediate right of Q.' Clue 2: 'T is between P and S.'
• Focus on the most direct and powerful clue first. The relationship between Q and R is fixed.
• Recognize the reciprocal nature of directions in a circle: 'Right of' for one person implies 'Left of' for the other. If R is to Q's right, then Q must be to R's left.
• Notice that this direct inference answers the question without needing the second clue. This is a common feature in reasoning puzzles.
• Use the remaining clues to build a complete picture only if necessary, or to double-check your initial conclusion.
