Question
In a container, the ratio of milk to water is 9:7. If 32
litres of water is added, the quantities of milk and water become equal. What is the total quantity of the mixture now?Solution
ATQ,
Let the initial quantity of milk and water be 9n and 7n litres respectively.
So,9n = 7n + 32
Or,2n = 32
Or, n = 16
Therefore, final quantity of mixture = 9n + (7n + 32) = 16 × 16 + 32 = 288 litres
