weight of the box + effective wieght of man = force applied by man

hw did u get this???

Figure shows a man of mass 60 kg standing on a light weighing machine kept in a box of mass 30 kg. The box is hanging from a pulley fixed to the ceiling through a light rope, the other end of which is held by the man himself. If the man manages to keep the box at rest, what  is the weight shown by the machine ? What force should he exert on the rope to get his correct weight on the machine ?

plzzzzzzzz   suggestif i hv done anything wrong

hey i got it d answer is 111/113

u get

80g/7 = M+m/M-m then componendo - dividendo gives u

m/M = 80g-7/80g+7

nw u take g = 9.8 m/s²

u will get m/M = 777 / 791

111* 7 = 777

113 * 7 = 791

so u get m/M = 111/113

if u find me right plzzzzzz   rate me...............
