    Question

    Quantity of milk is 40% more than that of water in 240

    litres mixture (milk + water). If 18 litres milk is added, then find the quantity of milk in the resultant mixture now.
    A 160 litres Correct Answer Incorrect Answer
    B 158 litres Correct Answer Incorrect Answer
    C 155 litres Correct Answer Incorrect Answer
    D 152 litres Correct Answer Incorrect Answer

    Solution

    Let the initial quantity of water be 'y' litres.
    Initial quantity of milk = '1.40y' litres
    So, y + 1.40y = 240
    Or, 2.40y = 240
    Or, 'y' = 100 litres
    Initial quantity of milk = 1.40 × 100 = 140 litres
    Therefore, final quantity of milk = 140 + 18 = 158 litres
