Moment is defined as the product of the force to the perpendicular distance from the pivot.

Total clockwise moments = 20(3)

Total anti-clockwise moment = 5(2) + 10(2)

Resultant moment = 20(3) - [5(2) + 10(2)] = 30Nm

NOTE : For the 10N force, the perpendicular distance from P is 2m since the line of action of the force is horizontal.

Hope it helps :)
