Question

A book seller receives net profit RS 1800 for 20 statistics books after allowing a discount of 15% and 2% for cash. Find the marked price or market price of a book?

Answer 1

Cost Price =  (17 * 0.98MP) - 1800

Step-by-step explanation:

N = 20

Profit = Rs. 1800

Let Market  Price  of the books be x.

Discount = 15%

Selling Price = x - (15/100)x = 0.85x

Selling Price of 20 Books = 20 * 0.85x = 17x

Cash discount = 2 %

Net amount received = 17 - (2/100)17x

= 17 * 98x/100

Cost Price =  17 * 98x/100  - 1800

Given the market price, CP can be calculated. Given the CP, MP can be calculated. Since both are not mentioned, the relationship is as above.
