Using the direct variation model, you can set up a proportion: 72 kg (body weight) is to 54 kg (water weight) as 180 kg (body weight) is to x kg (water weight). Solving for x gives you 135 kg of water in a person weighing 180 kg.
1 kg
That would be 2 Kg (on earth)
Sulfur is closely match this puzzle. The density of 2 kg sulfur is double than 1 kg water. So if you weigh the sulfur in immersed state, the weight of sulfur will be 1 kg. Sulfur will displace about 1 kg water and will lose the same weight. After taking out of water, 2 kg sulfur will be 2 kg only. When you burn the sulfur, it will combine with 2 kg oxygen and you will get 4 kg of sulfur bi oxide. So it is fairly close to the answer. 3 kg literally means more than 2 kg. May be you know the better answer.
