    Question

    The ratio of apples to oranges in a basket is 2:1. The

    average weight of oranges is (w тИТ 3) grams and the average weight of all fruits is (w + 3) grams. Find the average weight of apples.
    A w + 6 Correct Answer Incorrect Answer
    B w + 5 Correct Answer Incorrect Answer
    C w + 4 Correct Answer Incorrect Answer
    D w + 3 Correct Answer Incorrect Answer

    Solution

    Let apples and oranges be '2a' and 'a', respectively.
    Total weight of fruits = 3a ├Ч (w + 3) = 3aw + 9a
    Total weight of oranges = a ├Ч (w тИТ 3) = aw тИТ 3a
    So, total weight of apples = (3aw + 9a) тИТ (aw тИТ 3a) = 2aw + 12a
    Therefore, average weight of apples = (2aw + 12a) / 2a = (w + 6)
