L, P, R, V, X, Y and Z are sitting around a circular table facing the centre. Only one person sits between V and L, when counted from the right of V. Only one person sits between L and X. Only one person sits between V and Z. Only two people sit between R and X. Only one person sits between P and Z. Who sits to the immediate right and left of Y, respectively?

Fix V first and use the position of L relative to V from the right to lock down the circular positions counter-clockwise.
Fix V first and use the position of L relative to V from the right to lock down the circular positions counter-clockwise.
Step 1: Position V and L
Place V at the top. Since only one person sits between V and L when counted from the right of V, L is placed 2 positions to the right of V.
Step 2: Position X and Z
Only one person sits between L and X, and only one person sits between V and Z. This places X and Z at their respective positions on the circle.
Step 3: Position R, P, and Y
Using the remaining conditions (two people between R and X, one person between P and Z), Y is placed on the remaining seat. Checking Y's neighbors: Z is to its immediate right and V is to its immediate left.
A: V and Z is incorrect because V is to the left and Z is to the right of Y. B: V and X is incorrect as X is not adjacent to Y. D: X and Z is incorrect because X is at the bottom right.
C is correct because Z sits to the immediate right and V sits to the immediate left of Y respectively.
In circular arrangements facing the centre, 'immediate right' means counter-clockwise and 'immediate left' means clockwise.
