We know that the variation is proportianal, that is we can relate the quantities as:
where y is the mass of the body and x is the mass of water. From the values given we have that:
hence the constant of proportionality is 3/2. Now, if the mass of the water is 75, then the mass of the body is:
Therefore, the mass of the body is 112.5 kilograms
