    D 7:13 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Alcohol in the container = (3/4) × 60 = 45 liters Water in container = 60 - 45 = 15 liters Alcohol in 28 liters of mixture = 28 × (3/4) = 21 liters Water in 28 liters of mixture = 28 – 21 = 7 liters Required ratio = (45 – 21) : (15 – 7 + 28) = 2:3
