Eight persons A, B, C, D, E, F, G, and H are sitting around a circle facing the center. C is second to the right of A. E is opposite C. F is to the immediate left of E. B is to the immediate right of A. G is to the immediate left of D. Who is sitting to the right of D?
- (a)H
- (b)U
- (c)B
- (d)F
Answer
Why
Correct — D.
Rule: facing the centre, right is anticlockwise.
Number the seats 1 to 8 anticlockwise: right is +1, left is −1.
A = 1, B (immediate right of A) = 2, C (second right of A) = 3.
E (opposite C) = 7, and F (immediate left of E) = 6.
Seats 4, 5 and 8 remain for D, G and H.
G is on D's immediate left, and D = 4 or 8 would put G on C or E.
So D = 5, G = 4, H = 8.
The seat on D's right is 6: F → option (d).
Why the others are wrong
- (a)H — H takes seat 8, between E and A. It lands on D's right if F is wrongly put on E's right, a mix-up of directions.
- (b)U — U is not one of the eight people named, A to H, so U cannot sit anywhere in this circle.
- (c)B — B sits on A's immediate right, seat 2. D is at seat 5, with C and G between them.
Concept
In a circle, left and right depend on which way people face. Facing the centre, your right hand points anticlockwise round the table, seen from above. Facing outward, the two swap.
Pick one direction, number the seats that way, and turn every clue into arithmetic: right is +1, left is −1, and opposite is +4 in a circle of eight. Place the fixed clues first and fill the gaps last.
The question asks who sits to the right of D, without the word immediate. The key reads it as the next seat on D's right, which is F.
Key facts
- The final circle, anticlockwise from A: A, B, C, G, D, F, E, H.
- In a circle of eight, the person opposite sits four seats away in either direction.
- Facing the centre, right is anticlockwise and left is clockwise, seen from above.

Common traps
- Placing F on E's right, which lets H or E land on D's right
- Switching the direction convention partway through the clues
