    Answer:

    Number of story books bought = 100


    C.P. of each book = Rs. 135


    C.P. of all 100 books = Rs. (135×100)= Rs. 13500


    C.P. of 90 books = Rs. (135×90)= Rs. 12150


    Number of books donated = 10


    Number of books sold = 100-10=90


    Loss% in the transaction = 2%


    S.P. of all books = (C.P./100)(100-loss%)

                             =Rs. (12150/100×98)


    Thus, S.P. of each book


    = Rs. {(12150/100×98)÷90}


    = Rs. (12150/100×98/90)


    = Rs. 132.3

    Step-by-step explanation:

    nos of books=100

    cp=13500 total

    donation=10

    remaining books=90

    sp=cp-Loss%of cp

    sp=13500-2×135

    sp=13500-270

    sp=13230Rs

    Is the total sp of 90 books

    each book is sold at 13230/90Rs (use calculator to get result
