LET THE MASS OF OBJECT BE m AND HEIGHT BE h
GIVEN POTENTIAL ENERGY =200
                      m×g×h=200
                              m= \frac{200}{hg} ...........1
mow when it is raised to height h/4
then potential energy=m×g×h/4
                              = \frac{200}{hg} x \frac{h}{4} ×g
                              =50
