Algebra/Maths-Profit and loss


Even after giving a 10% discount on the printed price of an item the shopkeeper   gets a 20% profit. If the item is sold without the discount What is the % of profit on the printed price?

Lets say the price was P.
If a 10% discount is given, the price is 0.9P.
This is said to give a 20% profit.
20% of 0.9P is 0.18P.
If the paper were sold without the discount, that would mean we had the discount of 0.1P back again.  This makes the total profit 0.1P + 0.18P = 0.28P.
