# Mixture problem II

You have two large 2 liter container and a small cup of unknown volume. At the
beginning you have 1.2 liter of acid solution of unknown concentration in the left container, and
0.9 liter pure acid in the right one. We take one cup
of solution from the left container and putting it into the right one. After
that we take one cup of the resulting solution from the right container and put into
the left container. Finally we again put one cup solution from the left
container into the right one. At the end, we have 50% acid solution in the left
container and 80% acid solution in the right one. How large is the cup, and what
was the initial acid concentration in the left container?
