A Chemist has two solutions of alcohol. one has a 24% concentration and the other has 40% concentration. How many liters of each solution must be mixed to obtain 120 liters of a 30% solution?
24%---------40%----------30%
X------------120-x--------120
0.24x+0.4(120-x)=0.3*120
0.24x + 48 – 0.4x=36
-0.16x=-12
X=75 liters
120-75=45 liters
