Question
Given a mixture of 234 liters
consists of water and milk in the ratio of 21:5. If 1/2 of this mixture is removed and replaced with an equal quantity of milk, what will be the resulting ratio of water to milk in the final mixture?Solution
ATQ, Quantity of water in the final mixture = 31/26 × 117 = 21×4.5 = 94.5 litres Quantity of milk in the final mixture = 5/26 × 117 = 5×4.5 = 22.5 litres Quantity of milk added = (234/2) = 117 litres Therefore, required ratio = 94.5:(22.5 + 117) = 94.5:139.5 = 21:31
