M, N, O, X, Y and Z are sitting around a circular table facing the centre (but not necessarily in the same order).

- O is an immediate neighbour of Y.
- Z sits second to the right of O.
- X is the immediate neighbour of both M and N.
- M is not an immediate neighbour of O.

Who sits to the immediate left of Y?

Question

M, N, O, X, Y and Z are sitting around a circular table facing the centre (but not necessarily in the same order).

- O is an immediate neighbour of Y.
- Z sits second to the right of O.
- X is the immediate neighbour of both M and N.
- M is not an immediate neighbour of O.

Who sits to the immediate left of Y?

Accepted Answer

**Solution:**

1. All six persons M, N, O, X, Y, and Z sit around a circular table facing the centre.

2. Given that O is an immediate neighbour of Y, so O and Y sit next to each other.

3. Z sits second to the right of O. Since they face the centre, the right side is clockwise.

4. X is the immediate neighbour of both M and N, so X sits between M and N.

5. M is not an immediate neighbour of O.

**Step-by-step arrangement:**

- Place O and Y next to each other. Assume Y is at a position, then O is either immediate left or right of Y.

- Since Z is second to the right of O, count two seats clockwise from O to place Z.

- X must be neighbour to both M and N, so X is between M and N.

- M cannot be neighbour of O, so M cannot sit next to O.

**By trial and elimination:**

- Place Y at any seat.

- O is immediate left of Y (as per the conclusion).

- From O, second to right (clockwise) is Z.

- X sits between M and N.

- M is not neighbour of O.

Thus, the person sitting to the immediate left of Y is **O**.

**Answer:** O
