a mixture contain milk and water in the ratio is 7:4.on adding 9 litres of water ,the quantity of milk and water in the ration becomes equal.find the quantity of milk and water in the mixture

• ratio of milk:water 7:4
  quantity of milk in mixture 7x and that of water is 4x
  after adding 9 liters of water the ratio becomes 1:1
  => 7x-4x=9
  => x=3
  hence, amount of milk in mixture = 7*3=21.
  amount of water in mixture = 4*3=12.
