Question

25l milk water solution contain 20 percent water. how much water should be added the solution so that the ratio of milk to water in the results solution become 2:1

Answer 1

Water = x

x/25 = 20/100

x = (20 x 25)/100 = 500/100 = 5

milk = 25 - 5 = 20

now 20: 5

if we add 5l water more to this

20:10 = 2:1

So it should be 5l water to be added.
