Seven people H, I, J, K, O, P and Q are sitting around a circular table facing the center of the table. I sits third to the left of K. J sits second to the left of P. K is an immediate neighbour of both H and J. Q is not an immediate neighbor of I. How many people sit between O and J when counted from the right of O?

Explanation
The final clockwise arrangement of the seven people is K, H, O, I, P, Q, J.
The question asks for the number of people between O and J when counting from the right of O.
For a person facing the center of a circular table, their 'right' is the anti-clockwise direction.
Counting anti-clockwise from O, we encounter H and then K before reaching J.
Therefore, there are exactly two people (H and K) between O and J.
Why Other Options Were Wrong
Option A: This is an incorrect count based on the final arrangement.
Option B: This would be the answer if the question asked for the count from the left of O (clockwise). The people between O and J in the clockwise direction are I, P, and Q.
Option D: This is an incorrect count. It might result from misinterpreting the positions or the direction of counting.

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.
This type of question assesses logical deduction and spatial reasoning, which are critical thinking skills.
These skills are tested in the non-nursing, general aptitude sections of many competitive nursing entrance examinations.
Mastering these puzzles helps improve problem-solving speed and accuracy under exam conditions.
How to Approach the Question
First, identify the number of entities (7 people) and the setup (circular table, facing center).
Establish the directional rule: facing center means Left = Clockwise and Right = Anti-clockwise.
Begin with the most concrete clue. 'K is an immediate neighbor of both H and J' fixes a block of three people (J-K-H).
Draw a circle with 7 slots. Place the initial block and then use relative position clues (e.g., 'third to the left') to place others.
Use elimination clues (e.g., 'Q is not an immediate neighbor of I') to resolve ambiguities.
Once the final arrangement is set, re-read the question carefully to determine the start point (O), end point (J), and direction of counting (right of O, i.e., anti-clockwise).
