first you will find the actual amount of water and milk
the ratio is 5:3
let us consider the common number to be x
the quantity of milk = 5x
the quantity of water = 3x
5x+3x=64
8x=64
x=64/8
x=8
the quantity of milk is 5x
5(8)
40 liter
the quantity of water is 3x
3(8)
24 liter
in the second step will be the ratio 3:5
you interchange the value
the quantity of milk = 24 liter
the quantity of water = 40 liter
the amount of water is added =the quantity of water in 2 and step - the quantity of water in 1st step
40-24
16 liter
ans = the quantity of water required to change the ratio from 5:3 to 3:5 is 16 liter
