Question

cost price of 16 note book is equal to the price of 12 books find gain percent
​

Answer 1

answer:

    Let the Cost Price of one notebook be Rs 1.

 therefore , cost Price of 16 notebooks = Rs 16

            And Selling Price of 12 notebooks = Rs 16

                or selling Price of one notebook = 16/12

                therefore , Selling Price of 16 notebooks = 16/12*16

 Gain = selling Price of 16 Notebooks - Cost Price of 16 Notebooks

        =16*16/12 - 16

        =16*16 - 16*12 /12

        =16 (16 - 12)/12

        =16*4/12

        =16/3

hence gain % = Gain / Cost Price of 16 Notebooks *100

                    = (16/3)/16*100

                    =16/3*1/16*100

                   = 100/3

                   Gain %=33.33%
