Weight on mars is directly proportional to weight on earth... Therefore,

Wm α We => Wm = kWe, Where Wm = Weight on mars, We = Weight on earth, k = constant of proportionality.

For Wm = 50 pounds, We = 150 pounds;

k = Wm/We = 50/150 = 1/3
Now, for 120 pounds on earth;

Wm = k*We
Substituting;
Wm = 1/3 * 120 = 40 pounds
