Question
Four people sit around a square table, one on each side, facing the centre. P is opposite Q and R is to the immediate left of P. Who is opposite R?
Options
- P
- Q
- S
- Nobody
Show the answer and the worked solution
Correct answer: C. S
Worked solution
- Number the seats 1–4 clockwise, with P at 1 and Q opposite at 3.
- Facing the centre, P's left is clockwise, so R = seat 2.
- The remaining seat 4 holds S, and seat 4 is opposite seat 2.
- So S sits opposite R.
Answer: S.
The idea
Fix one person, place their opposite, then use the left-right rule. Facing the centre, left is clockwise.
Shortcut. With P and Q opposite, R and S take the other two seats, which face each other — so S is opposite R whichever side R is on.
Common trap. "Nobody" — assuming S's seat is unknown because S is never mentioned; with three seats filled, S takes the fourth, opposite R.
