The final solution is 22 l cantaning 90% water.
Amount of water =90% of 22 = 19.8 liter
Amount of milk = 22–19.8 =2.2 liter
Initially %of milk in solution = 100 - 89= 11%
Let the initial amount of solution is x
The amount of milk will remain same in both case only only water is added to it.
The amount of milk = 11% of X = 2.2
=> X = 2.2*100/11
=> X = 20 liter
Hence amount of water added = 22 -20 = 2 liter
