Difficulty: Medium
Correct Answer: N and P
Explanation:
Introduction / Context:
With four people around a square/round table, “partners” are the two who sit opposite. Right/left are taken with everyone facing inward.
Given Data / Assumptions:
Concept / Approach:
Place N, then put M immediately to N’s right. Separately ensure P is immediately to O’s left. Fit the four around the table and identify opposite seats.
Step-by-Step Solution:
A consistent clockwise order is: N, O, P, M.Check: M is right of N (counterclockwise neighbor) — yes (M is before N when listing clockwise).P is left of O (clockwise neighbor) — yes (P follows O clockwise).Opposite pairs are (N, P) and (O, M).
Verification / Alternative check:
Trying other rotations yields the same opposite pairing structure.
Why Other Options Are Wrong:
They are adjacent pairs, not opposites, or they conflict with right/left constraints.
Common Pitfalls:
Using classroom right/left instead of inward-facing circular right/left.
Final Answer:
N and P
