Passage

Directions: Read the following information and answer the questions that follow: A milkman takes three tanks A, B and C of milk having 300 litres of milk in each tank. The milkman takes x litres of milk from the first tank and replaces with water. Then, the milkman takes (x + 30) litres of milk from the second tank and replaces with water. Finally the milkman takes (x + 60) litres of milk from the third tank and replaces with water. The ratio of total milk in the three tanks to total water in the three tanks is 7:23.

What will be the ratio of milk to water in a container having 200 litres of milk, if x litres of milk is replaced with water and the process is repeated three times?
