After allowing a discount of 10% on the marked price, a trader still makes a gain of 17%. By what per cent is the marked price above the cost price?


Let’s assume Cost Price of Product to be Rs.100.


Given he gains 17% on selling price would be


Selling Price = (100 + 17% of 100) = Rs.117


Discount = 10%


Let × be the marked price.


Market Price – Discount = Selling Price


x- (10% of x) = 117


× – x/10 = 117


9x/10 = 117


× = 130


Cost price is 100


Selling price is 117


Marked price is 130


So, Market Price is 30% above Cost Price.
