**Steve**, Tuesday, January 29, 2013 at 11:42amwork with the amount of alcohol in each part. It has to add up to the total alcohol.

.25x + .75(90-x) = .60(90)

x = 27

so, 27 qt @ 25% and 63 qt @ 75%

**Steve**, Tuesday, January 29, 2013 at 12:14pmIf you let x be the amount of 25% solution, then .25x is the amount of alcohol in that solutions.

Since there are 90 qts in all, 90-x is the amount of the 75% solution. .75(90-x) is the amount of alcohol in that solution.

Add up the two amounts of alcohol, and it must equal the amount of alcohol in 90 qts of 60% solution.

Ta-daa
