    1033.75

    B.

    1023.75

    C.

    1043.75

    D.

    1048.75

    Correct option is A

    Given:

    Mohan bought 52 books at Rs 1130 each

    Mohan bought 44 books at Rs 920 each

    Formula Used:

    Average price per book = Total CostTotal Number of Books\frac{\text{Total Cost}}{\text{Total Number of Books}}​​

    Solution:

    Total cost from the first shop = 52×113052 \times 1130​ = 58760

    Total cost from the second shop = 44×92044 \times 920​ = 40480

    Total cost = 58760 + 40480 = 99240

    Total number of books = 52 + 44 = 96

    Average price per book =9924096 \frac{99240}{96}​ = 1033.75
