SUBTOPICS:DISCOUNT
Marked Price:
In big shops and departmental stores, every article is tagged with a card and its price is
written on it. This is called the marked price of that article, abbreviated as MP.
For books, the printed price is the marked price.
List Price:
Items which are manufactured in a factory are marked with a price according to the list
supplied by the factory, at which the retailer is supposed to sell them. This price is
known as the list price of the article.
Discount:
In order to increase the sale or clear the old stock, sometimes the shopkeepers offer a
certain percentage of rebate on the marked price. This rebate is known as discount.
Notes:
The discount is always reckoned on the marked price.
Selling price = (marked price) - (discount)
'selling price' is the amount you actually pay for the thing when you purchase.
'marked price' is the general price of the thing without any discount.
'discount' is a percentage of the marked price.
