Writing Project 40:

Mixture Problem III

We have three glasses containing acid solution each. If we would put the first and the second together, we would get 200 ml of a 50% solution. If we would put the first and the third glass together, we would get 300 ml of a 60% solution. If we would put the contents of the second and third glass together, we would get 250 ml of a 70% solution.
