Four colleagues L, M, N and O, are sitting around a square table facing outward. L is sitting to the immediate left of M. N is sitting to the immediate right of O. Who is sitting to the immediate right of L?

There are four people sitting around a square table facing outwards (away from the center).
Facing outward means:

* For any person, moving clockwise means moving towards their left.
* Moving counter-clockwise means moving towards their right.

Let's place them according to the given statements:

1. "L is sitting to the immediate left of M."
If M is placed at any position, L is to the immediate left of M. Since they face outwards, immediate left means moving clockwise. So, L is next to M in the clockwise direction.
2. "N is sitting to the immediate right of O."
For those facing outwards, immediate right means counter-clockwise. This means O is next to N in the clockwise direction.

Since there are only 4 seats, the positions in clockwise order must be: M, L, O, N.
Let's double check:

* Clockwise from M is L (L is to the immediate left of M) - True.
* Clockwise from O is N, which means counter-clockwise from O is N (N is to the immediate right of O) - True.

Now we need to find who is sitting to the immediate right of L.
Since the arrangement facing outward has right as counter-clockwise, the person to the immediate right of L is the one preceding L in the clockwise sequence, which is M.
