Question
A drum contains 400 liters of a mixture of milk and
water in the ratio of 5:3. If x liters of milk and 2x liters of water are added to the mixture, then both milk and water become equal in the final mixture. Find the amount of milk left.Solution
ATQ, Initial amount of milk = 400 × 5/(5 + 3) = 400 × 5/8 = 250 liters Initial amount of water = 400 – 250 = 150 liters (250 + x) / (150 + 2x) = 1/1 2x – x = 250 – 150 x = 100 The amount of milk left in the drum = 250 + 100 = 350 liters
