    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Initial quantity of ink in the jar = 180 × 4/6 = 120 liters

    Initial quantity of water in the jar = 180 – 120 = 60 liters

    (120 + 24)/(60 + 36) = x/6

    144/96 = x/6

    3/2 = x/6

    x = (3 × 6)/2 = 18/2 = 9
