Another machine uses an input of 200 newtons to produce an output force of 80 newtons what is the mechanical advantage of this machine

If the input machine produces an output of 80 Newtons, then the mechanical advantage is that it produces work. If the required output must be 80 Newtons, then the input force is desirable having 100 percent production of force even though it requires a large amount of input to produce 80 Newtons of force.
