A chemist has three different acid solutions. The first acid solution contains 15 % acid, the second contains 30 % and the third contains 50 %. He wants to use all three solutions to obtain a mixture
of 96 liters containing 40 % acid, using 3 times as much of the 50 % solution as the 30 % solution.
How many liters of each solution should be used?
liters of 30 % solution,
The chemist should use
liters of 15 % solution,
and
liters of 50 % solution.
