Did you try to solve the problem?

If so, you should've posted what you tried first.

Did you try balancing the moments?

Clockwise moment = Anticlockwise moment

And;

Moment of a force = Force x Perpendicular distance from pivot.

but remember to divide it by two, because the question says on each handle.
I am just wondering if the height difference makes any changes.

I don't think so. M = F x Perp. D dosen't involve distances that are parallel to the force.
