Hi,

using the example of forming a 100L solution         

Let x and (100-x)represent the amount of the 75% and 50% solutions respectively

Mixing to the form 100L of the 60% solution 

 .75x + .50(100L-x) = .60*100L

            .25x = .10*100L

               x = 10L/.25 = 40L, the 75%,   60L, the 50%

 Ratio of the 50% alcohol be mixed with 75% alcohol

                   60/40 = 6/4 = 3/2 OR 3:2
