None of theseExplanation
Since 729 ml of mixture contains milk and water in the ratio 7 : 2, Amount of milk = (7/9) × 729 = 567 ml Amount of water = 729 – 567 = 162 ml Let, x ml of water is added. ⇒ 567 : (162 + x) = 7 : 3 Solving, x = 81 ml Hence, we will need to add 81 ml of water to the mixture to make the ratio of milk and water as 7 : 3.Related questions
