    Question

    In a 180-liter mixture, there is a ratio of 11:7 between Milk and Glucose. How much additional Glucose should be added to the mixture so that the quantity of glucose becomes 50% of the resultant mixture?

    A 40 liters Correct Answer Incorrect Answer
    B 30 liters Correct Answer Incorrect Answer
    C 45 liters Correct Answer Incorrect Answer
    D 56 liters Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, Quantity of Glucose in the initial mixture = 180 × (7/18) = 70 liters Quantity of Milk in the initial mixture = 180 × (11/18) = 110 liters Since, we’re not adding Milk, 110 litres of Milk will represent 50% of the new mixture. So, total quantity of resultant mixture = 110 ÷ 0.5 = 220 liters Quantity of Glucose to be added = 220 – 180 = 40 liters
