OK, you need to set up two simultaneous equations:
Let X = number of liters to be added
Let Y = total volume of 60% alcohol solution
Eq. 1: .70 X + .15 (30) = .60 Y
Eq. 2: X + 30 = Y
Substitute Eq. 2 into Eq. 1: .7X + 4.5 = .6 (X + 30)
.7X + 4.5 = .6X + 18
multiply both sides of the equation by 10:
7X - 6X = 180 - 45
X = 135 liters will have to be
added to get 60% sol'n.
The total volume left will be Y = 135 + 30 = 165 liters

Big fat hairy thumbs up to Doug R.
That brought back nasty ol' flashbacks from chemistry and concentration addition equations.

I have not done this kind of question in so long, but my daugher soon enough will be asking. Is the answer 20.25 liters?

you must be mixing what is called Everclear up here. college kids use it but it is deadly. I hope someone knows and can get the advice also. Everclear is really hot stuff and CHEAP.
