Discounts

Are you familiar with daily “special sales” in stores, shops, malls and online shopping sites?

Sometimes, to increase sales or dispose off old stock, the
sellers attract customers to buy goods by offering a certain
type of reduction in the Marked Price (MP) or List Price (LP)
of goods. This type of reduction given on the marked price
is called a discount.
It is generally given as a certain percentage of the marked

price. The discounted price is called the sale price or selling price (SP) of the article.
So, Discount = Marked Price (MP) – Selling Price (SP)

Discount
Rate of Discount or Discount % = × 100%
MP
If we have given discount %, then
×
MP (100 − Discount%) 100 × SP
l SP = l MP =
100 100 − Discount%
