Question

After allowing a discount of 10% on the market price, Rohan ,the shopkeeper still makes a gain of 17%.by what percent is the marked price above the cost price?

Answer 1

Hlw mate!!

Let the cost price be 100 Rupees.There is gain of 17% so, Selling price will be 117 Rupees.Sp=117

Let marked price be x

Then 90%of X=117

(90/100)x=117

x=117*100/90

=130

Above cost price=130-100=30

So, marked price is 30 rupees more than CP.

So, shopkeeper must mark his good's price 30% more than cost price.

Hope it helpful
