    Question

    The average marks of a class of 40 students were 75.

    When the marks of 5 students were removed, the average marks of the remaining students became 72. What were the average marks of the 5 students whose marks were removed?
    A 55 Correct Answer Incorrect Answer
    B 77 Correct Answer Incorrect Answer
    C 96 Correct Answer Incorrect Answer
    D 87 Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Total marks of 40 students = 40 X 75 = 3000 Total marks after 5 students were removed = 35 X 72 = 2520 So, total marks of the 5 removed students = 3000 - 2520 = 480 So, required average = 480 Ă· 5 = 96 marks
