    Question

    Mona ranked is 9th from the top and 36th from the bottom in a class. How many students are there in the class?

    A.

    46

    B.

    44

    C.

    45

    D.

    47

    Correct option is B

    Given:  Mona ranked is 9th from the top and 36th from the bottom in a class. 
    Formula: Total students = Rank from the top + Rank from the bottom - 1
    Mona's rank from the top = 9th
    Mona's rank from the bottom = 36th
    Apply the formula:
    Total students = 9 + 36 – 1 = 44
    Thus, the total number of students in the class is 44.
    Thus, the correct option is (b) 44.
