Question

A shopkeeper sold an electric press for RS1700 to a customer at a discount of 15% .what is the market price of an electric press?

Answer 1

The data is not enough. All we can calculate is the selling price before the discount. We can calculate the original selling price of the product is 2000, because the 15% off 2000 gives you 300 which gives you 1700. If the selling price is what the shopkeeper bought it for, then the Market Price would also be 2000. Although, in this case the Shopkeeper goes into a 15% loss.

Answer 2

(Discount price/original price)*100=percentage
{(original price-1700)/original price}*100=15
1-1700/original price=15/100
1-15/100=1700/original price
(100-15)/100=1700/original price
original price=1700*100/85
=2000Rs
