Explanation

The quantity of milk in the mixture is 7/(7+2) X 729 = 7/9 X 729 = 567mL The quantity of water then shall be 729 - 567 = 162mL If the final mixture would contain half milk and half water, there must be equal quantity of both. So in order to make up for water, we'll need to add 567mL - 162mL= 405mL of water
