Find the effort required to lift a load of 50 `kg_(wt)` using a simple machine if its mechanical advantage is

The effort measured in S.I. system in lifting a load through a simple machine is numerically equal to its mechanical advantage. If the mechanical advantage of the machine is increased by 20%, the same effort can lift a load of 12 kgwt. Find the magnitudes of the effort and the original load. (Take g=10 ms^(-2) )

The effort applied to lift a 60 N box using a simple machine is 45 N. Find the MA of the machine.
