Study the following information carefully and answer the given questions.
Eight persons - A, B, C, D, P, Q, R, and S are sitting around a circle table, but not necessarily in the same order. Four of them is facing inside the center and four of them is facing outside the center.
Both the immediate neighbors of A face away from the center. Q faces towards the center and sits to the immediate left of B. A and B face towards the center and sit opposite to each other. Three people sit between Q and R. C and B are the immediate neighbors of D who faces away from the center. C faces away from the center. S is not an immediate neighbor of A.
Which of the following statements is correct about P?
Correct Answer :
P sits second to the left of R
Solution :
The correct answer is: "P sits second to the left of R"
We have eight persons — A, B, C, D, P, Q, R, S — sitting around a circular table. Four face inward (towards center) and four face outward (away from center). Let's decode each clue step by step.
Step 1 — Establish the A–B relationship
Clue: "A and B face towards the center and sit opposite to each other."
So A and B are on diametrically opposite seats, both facing inward.
Label seats 1–8 going clockwise. Place A at seat 1 and B at seat 5 (opposite).
Step 2 — Place Q relative to B
Clue: "Q faces towards the center and sits to the immediate left of B."
In a circular table, "immediate left" of B (seat 5) when facing inward means seat 4.
So Q is at seat 4, facing inward.
Step 3 — Handle A's neighbors
Clue: "Both the immediate neighbors of A face away from the center."
A is at seat 1. Neighbors are seat 8 (left) and seat 2 (right). Both face outward.
Step 4 — Place D, C, and B's neighbors
Clue: "C and B are the immediate neighbors of D who faces away from the center."
So D's immediate neighbors are C and B. Since B is at seat 5, D must be adjacent to B — either seat 4 or seat 6.
Seat 4 is already taken by Q, so D is at seat 6, facing outward.
D's neighbors are B (seat 5) and C — so C is at seat 7.
Step 5 — Determine C's facing direction
Clue: "C faces away from the center."
So C at seat 7 faces outward.
Step 6 — Count facing directions so far
Inward (towards center): A (seat 1), Q (seat 4), B (seat 5) → 3 inward so far.
Outward (away from center): seats 2, 8 (A's neighbors), D (seat 6), C (seat 7) → 4 outward so far.
We need exactly 4 inward and 4 outward total. One more person must face inward.
Step 7 — Place R using the Q–R clue
Clue: "Three people sit between Q and R."
Q is at seat 4. Counting 3 people between them (going clockwise: seats 5, 6, 7 are between) → R is at seat 8.
Or going counter-clockwise from Q (seat 4): seats 3, 2, 1 are between → R is at seat 8 from the other side too — wait, let's check both:
— Clockwise from Q (seat 4): 4 → 5 → 6 → 7 → 8. Three seats between = seats 5, 6, 7. So R = seat 8. ✓
— Counter-clockwise from Q (seat 4): 4 → 3 → 2 → 1. Three seats between = seats 3, 2, 1. So R = seat 8 (from the other arc end). Same answer! ✓
So R is at seat 8, which was already established to face outward (A's neighbor).
Step 8 — Place the remaining persons: P and S
Seats filled: 1(A), 4(Q), 5(B), 6(D), 7(C), 8(R).
Empty seats: 2 and 3.
Remaining persons: P and S.
Clue: "S is not an immediate neighbor of A."
A is at seat 1. A's immediate neighbors are seat 8 (R) and seat 2.
So S must NOT be at seat 2. Therefore S is at seat 3 and P is at seat 2.
Step 9 — Determine P's facing direction
We need exactly 4 inward-facing persons. Currently inward: A(1), Q(4), B(5) = 3.
One of the remaining (P at seat 2, S at seat 3) must face inward.
P is at seat 2 — A's neighbor — and A's neighbors face outward (from Step 3).
So P faces outward and S faces inward (the 4th inward person). ✓
Step 10 — Final arrangement (clockwise)
Seat 1: A — inward
Seat 2: P — outward
Seat 3: S — inward
Seat 4: Q — inward
Seat 5: B — inward
Seat 6: D — outward
Seat 7: C — outward
Seat 8: R — outward
Step 11 — Verify the correct option
Option: "P sits second to the left of R."
R is at seat 8. Moving to the left (counter-clockwise) from R:
— 1st to the left of R = seat 7 (C)
— 2nd to the left of R = seat 6 (D)
Hmm — let's reconsider direction. In circular arrangements, "left" depends on which way the person is facing. For outward-facing people, their left is in the clockwise direction (from our bird's-eye view).
R (seat 8) faces outward. When R faces outward (away from center), R's left is clockwise → seat 1 is 1st to R's left, seat 2 is 2nd to R's left.
Seat 2 = P. ✓
So P sits second to the left of R is confirmed correct!
Checking the other options quickly:
• "P sits second to the right of R" — 2nd to R's right clockwise from R's outward perspective would be seat 6 (D). ✗
• "Three persons sit between P and C" — P(2) to C(7): seats 3,4,5,6 between them = 4 persons. ✗
• "Two persons sit between P and A" — P(2) and A(1) are immediate neighbors; 0 persons between them. ✗
Therefore, the correct statement about P is: "P sits second to the left of R."
