@LukeAlmighty Agreed.
This one's tricky though, which is exactly why it's being showcased, and I believe the answer is 100N.
@skiizm @LukeAlmighty Consider this part of the image.
The scale isn't moving.
It might as well be tied to a wall.
Then it's obvious, it will show 100N.
Another way to think about it:
Since there is an equilibrium, that must mean that the weights are being held up by a force of 100N, so that's what the scale should show.
@ergo @skiizm @LukeAlmighty They push, it's called the normal force.
@ergo @skiizm @coded_artist
You cannot pull anything without another force acting against you (if you want it to stay in place). That force can be either created by a wall, or by another weight. But that force will be equal to the force you pull the weight with.

It's 100. Sorry.
@skiizm @LukeAlmighty The scale here is essentially part of the string.
The tension on the string is 100N to hold the weights.
So that's what the scale will show.
I don't know how else to explain it.
