    B.

    3.68

    C.

    4.95

    D.

    6.52

    Correct option is C

    Formula Used:  

    Mean = (X×F)F\frac{\sum(X \times F)}{\sum F}​​

    Solution:

    (X×F) \sum (X \times F) = (15 + 6 + 40 + 8 + 30) = 99

    F{\sum F} = (5+3+4+2+6) = 20

    Mean = 9920\frac{99}{20} = 4.95

    Thus the correct answer is (C)
