Question

The marked price of a book is Rs 2000. If it is sold at 15% discount and 25% profit, find the discount amount, selling price and cost price.
​

Answer 1

Answer:

Explanation:

Marked Price ( MP) = Rs. 2000

discount rate = 15 %

profit rate = 25 %

Discount amount = discount % of MP

                             = 15 / 100 * 2000

                             = Rs. 300

Now

Selling Price ( SP) = MP - discount amount

                             = Rs. ( 2000 - 300 )

                            = Rs. 1700

Also ,

$Cost Price ( CP) \\= \frac{SP * 100 }{100 + P percent } \\= \frac{1700 *`100}{100 + 25} \\=Rs. 1360$

hope it will help :)
