By selling a product a seller is gaining 10% on selling price. If he sells that product Rs.80 less, he would have been losing 10%. What is the cost price?
RE: By selling a product a seller is gaining 10% on selling price. If he sells that product Rs.80 less, ...
Let X be the original price of the product. If the product is sold at Rs. 80 less then original price he would suffer 10 loss. So it will be (x-80) x-10x/100 or x-800 9x/10 or 10x-9x 800 or x 800
So the original sot of product is Rs. 800 and Selling price is (10 in profit) Rs. 880
