    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?
    A 21:31 Correct Answer Incorrect Answer
    B 41:31 Correct Answer Incorrect Answer
    C 22:51 Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    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
