    Question

    Rahul and Tarun scored marks in the ratio 6:5. If Rahul

    had scored 4 marks more and Tarun had scored 5 marks less, the ratio of their marks would have become 7:5. Find the original marks obtained by Tarun.
    A 75 Correct Answer Incorrect Answer
    B 50 Correct Answer Incorrect Answer
    C 45 Correct Answer Incorrect Answer
    D 60 Correct Answer Incorrect Answer
    E 55 Correct Answer Incorrect Answer

    Solution

    Marks obtained by Rahul and Tarun be ‘6x’ and ‘5x’ respectively.

    So, (6x + 4)/(5x – 5) = 7/5

    6x + 4 = 7x – 7

    x = 11

    Marks obtained by Tarun = 5x = 55
