Question

A dealer earns a profit of 12% after selling a book at 10% discount on the printed price. Find the ratio of the C.P. and the printed price of the book.​

Answer 1

Answer:

45:56

Step-by-step explanation:

Let the CP of book = Rs.x

Then, SP of book = (100+12)×x/100=112x/100

Now. the printed price = Rs.y

Then, after discount, the SP

=(100-10)×y/100= 90y/100

Since, both SP are same.

112x/100=90y/100

x/y= 45/56

x:y= 45:56
