    B 130 Correct Answer Incorrect Answer
    C 140 Correct Answer Incorrect Answer
    D 150 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Quantity of milk in the initial mixture = 100 × 0.40 = 40 litres Quantity of water in the initial mixture = 100 – 40 = 60 litres Quantity of water is unchanged in the final mixture. So, Quantity of final mixture = (60/25) × 100 = 240 litres Quantity of milk in final mixture = 240 – 60 = 180 litres Value of ‘x’ = 180 – 40 = 140
