acid
percent ---------------- quantity
Solution I 50.00% ---------------- x liters
Solution II 70.00% ------ 60 - x liters
Mixture 60.00% ---------------- 60
60
50.00% x + 70.00% ( 60 - x ) = 60.00% * 60
50 x + 70 ( 60 - x ) = 3600
50 x + 4200 - 70 x = 3600
50 x - 70 x = 3600 - -4200
-20 x = -600
/ -20
x = 30 liters 50.00% Solution I
30 liters 70.00% Solution II
