Eight students, A, C, D, H, K, R, S and V are sitting around a circular table facing the centre (not necessarily in the same order). Four people are sitting between C and V from the right of C, while two people are sitting between V and S from the left of V. A is sitting opposite to S, while D is sitting opposite to K. If R and D are neighbours, then which of the following is the neighbour of H?

Option 2 : C and S

Eight students: A, C, D, H, K, R, S and V

1) Four people are sitting between C and V from the right of C, while two people are sitting between V and S from the left of V

2) A is sitting opposite to S, while D is sitting opposite to K

There are two possible cases:

Case I:

Case II:

3) R and D are neighbours

This statement is violated in case II, so it is eliminated

In case I, R will occupy the position to the immediate right of D and H will occupy the remaining position

Thus, the final arrangement is:

Hence, C and S is the neighbour of H
