No, The answer would be 100kN down, if my calculations are right.
Why are you taking moments anyways? It is asking for the magnitude of the force in the member MN.

If you want an explanation:
Split member ON into components and solve sum of forces = 0 vertically and horizontally. (Start with horizontal first so that you can get force of ON).
