Question 251982
I'll try this one because it is a little different from the other mixture problems.
solution x ratio is 3:2 making it 3 /5 alcohol
solution y is 3:4 making it 3/7 alcohol
Let the amount of solution x and solution y be a
(3/5)a+ya=(3/7)*2a
a21/35 +35ay/35=6*5a/35
multiply by 35
21a+35ay=30a
divide by a
21+35y=30
35y=9
y=9/35
so the solution y is 9/35 alcohol and 26/35 water
so the ratio is 9:26 A:W
