Difficulty: Medium
Correct Answer: Bobby
Explanation:
Introduction / Context:
We must place six named friends around a circular table (all facing the centre) so that the local adjacency constraints are satisfied. Then we identify the person to Michael’s immediate right (clockwise side).
Given Data / Assumptions:
Concept / Approach:
For circular arrangements facing the centre, “left of X” means the next counterclockwise seat from X. “Between” means immediate adjacency on both sides. We construct the ring by chaining the mandatory adjacencies, watching for consistency and avoiding contradictions.
Step-by-Step Solution:
Verification / Alternative check:
Try the mirror possibility for Michael’s neighbours (swap Bobby and Johnny). In each consistent configuration, the person to Michael’s immediate right is the same: Bobby. Multiple symmetric solutions (rotations) exist, but they all give the same right neighbour for Michael.
Why Other Options Are Wrong:
Common Pitfalls:
Mixing up “left of” with “right of” when everyone faces the centre; also reading “between” as a broad positional description rather than immediate adjacency.
Final Answer:
Bobby
