A chemist has three different acid solutions. The first acid solution contains 25 % acid, the second contains 40 % and the third contains 60 % . He wants to use all three solutions to obtain a mixture of 108 liters containing 45 % 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 40 % solution, and liters of 60 % solution.
