Bottle X contains 10% acid and bottle Y contains 20% acid. In what ratio, of the quantity of bottle X to the quantity of bottle Y, do I need to mix the liquid from the two bottles if I want to create a mixture that is 16% acid?
+128406 Let us suppose that the total amount we wish to make is 100 liters
Then let the amt of liquid from the 15% bottle = x and the amt from the 20% bottle = 100 - x
So...we have
.15x + .20 (100 - x) = .16 (100)
.15x +20 - .20x = 16
-.05x + .20 = 16
-.05x = .16 -.20
-.05x = -. 4
x = 80
100 - x = 20
X : Y = 80 ; 20 = 4 : 1
