A chemist has three different acid solutions. The first acid solution contains 20% acid, the second contains 30% and the third contains 50%. They want to use all three solutions to obtain a mixture of 85 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? The chemist should use liters of 20% solution, liters of 30% solution, and liters of 50% solution.
