    Question

    If 97% of students are present in a class and 12 students are absent, find the total number of students in the class.

    A.

    400

    B.

    700

    C.

    800

    D.

    600

    Correct option is A


    Let the total number of students be X.
    If 97% are present, 3% are absent:
    3% of X=12
    3 / 100 × �� = 12
    �� = 12 × 100 / 3 = 400
    Thus, the correct answer is 400.
