Wouldn’t it be 100, same as the mass being lifted (well more really, depending on the acceleration of that mass)?

No, the other commenters are right — it’s between 100 and 150 depending on the angle. And it’s like this because we have 50 N + 50 N on both sides of the top pulley (classic pulley thing) + 50 N more attached to it at the bottom. Kinda confusing at first, not gonna lie :)
