A chemist has three different acid solutions. The first acid solution contains 25% acid, the second contains 40% and the third contains 60 %. They want to use all three solutions to obtain a mixture of 96 liters containing 50% acid, using 3 times as much of the 60 % solution as the 40% solution. How many liters of each solution should be used? The chemist should use liters of 25% solution, liters of 60% solution. liters of 40% solution, and
