Direction: Study the following information carefully and answer the given question.
Eight persons — A, B, C, D, P, Q, R and S — are seated around two inscribed square tables such that four persons sit at the four corners of the inner square and four persons sit at the four corners of the outer square. The persons seated at the inner square and the persons seated at the outer square face each other.
C faces the one who sits 2nd to the right of S. Q is an immediate neighbour of neither S nor C. D faces R and is an immediate neighbour of Q. A sits immediately to the left of R. B faces P. B and C are not immediate neighbours. Neither P nor A faces outside.
Who among the following sits 3rd to the left of the one who faces D?
- A.
C
- B.

- C.
A
- D.
P
- E.

Correct answer: A
Concept
In a two-square (inner + outer) seating puzzle, each inner-square person and the outer-square person directly across from them form a facing pair, so “X faces Y” fixes both seats relative to each other. To place everyone, start from the clue that anchors a facing pair to a direction word (“2nd to the right”), then chain each “faces” and “immediate neighbour” clue. Remember the mirror rule: people on the inner square face outward and people on the outer square face inward, so left/right for the two squares run in opposite senses.
Applying the clues step by step
“Neither P nor A faces outside” means P and A face inward, so both P and A sit on the outer square.
“D faces R” makes D–R a facing pair; with “A immediately left of R” and “B faces P” we place R, A, P on the outer square and D, B on the inner square.
“D is an immediate neighbour of Q” puts Q on the inner square next to D; “Q is an immediate neighbour of neither S nor C” then forces S onto the inner square and C onto the outer square.
“C faces the one 2nd to the right of S” together with “B and C are not immediate neighbours” fixes the only consistent rotation: C ends up facing Q, and the four outer seats read A, R, C, P with the inner seats S, D, Q, B opposite them.
Answering the question
D and R are a facing pair, so the one who faces D is R. Counting to the left of R along the outer square gives A (1st), P (2nd) and then C (3rd), so the person 3rd to the left of the one who faces D is C.
Cross-check
Verify every clue against the final layout: C faces Q, and Q is indeed 2nd to the right of S ✓; D faces R ✓; B faces P ✓; A is immediately left of R ✓; Q’s neighbours are D and B (neither S nor C) ✓; B’s neighbours are S and Q, so B and C are not adjacent ✓. Every condition holds, so the person 3rd to the left of the one who faces D is C.
