a type of milk contains 8% water. what quantity of pure milk should be added to 20 litres of this milk to reduce water to 5%?

• Ans=12 liters
  Quantity in 20 liters of Milk:Water = (92*20/100):(8*20/100)=18.4 : 1.6
  If water is to be 5%, then total quantity= 1.6*100/5= 32 lit.
  So quantity of pure milk required to add= 32-20= 12 lit.
