    Question

    If 'A' = (2/5) of 'B', 'B' = (3/4) of 'C', then find the

    value of (A + B) :(B + C) .
    A 4:7 Correct Answer Incorrect Answer
    B 3:5 Correct Answer Incorrect Answer
    C 5:6 Correct Answer Incorrect Answer
    D 3:7 Correct Answer Incorrect Answer

    Solution

    Let 'B' = 5y

    Therefore, 'A' = 5y X (2/5) = 2y

    And, 'C' = (5y) X (4/3) = (20y/3)

    Therefore, (A + B) = 2y + 5y = 7y

    And, (B + C) = 5y + (20y/3) = (35y/3)

    Therefore, (A + B) :(B + C) = 7y:(35y/3) = 3:5
