Hmm so to find out the percentage of water in the body we take the 62 kg of water and divide that by 93 kg:
62/93 = 2/3 or 66.66666% of their mass is water

so to find how much water is the 75 kg person we multiply that by the 2/3.

75*(2/3) = 50

So the 75 kg person has 50 kg of water in them.

W = k*M
62 = k*93
k = 62/93 = 2/3
W = 2*75/3 = 50kg
