Question

    In a tank, milk and water are mixed in the ratio 5:4. When

    A 200 litres Correct Answer Incorrect Answer
    B 160 litres Correct Answer Incorrect Answer
    C 360 litres Correct Answer Incorrect Answer
    D 250 litres Correct Answer Incorrect Answer

    Solution

    ATQ,

    Milk : Water = 5:4 → Total = 9 parts

    Let total = 9x

    → Milk = 5x, Water = 4x

    Add 36 litres of water:

    → New water = 4x + 36

    → New ratio = 5x : (4x + 36) = 5 : 6

    Original mixture = 9 × 36 = 324 litres

    Final = 324 + 36 = 360 litres
