    C 39 Correct Answer Incorrect Answer
    D 20 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Quantity of milk in the initial mixture = 130 × 0.35 = 45.5 litres Quantity of water in the initial mixture = 130 – 45.5 = 84.5 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (84.5/50) × 100 = 169 litres Quantity of milk in final mixture = 169 – 84.5 = 84.5 litres Value of ‘x’ = 84.5 – 45.5 = 39
