An industrial chemist will mix two acid solutions. One is 37% solution and the other is a 27% solution. How many liters of each should be mixed to get 50 liters of a 36% acid solution?

Answer 1

x = liters of 37% acid solution
Other = (50 - x) = liters of 27% solution
37x + 27*(50 - x) = 50*36
37x + 1350 - 27x = 1800
10x = 450
x = 45 liters
45 liters of 37% acid and 5 liters of 27% acid.

Answer 2

45 liters of 37% acid and 5 liters of 27% acid.
