Before you study What is Discount, you are adviced to read:
What is Selling Price or SP and What is Marked Price ?
What is Discount
In order to attract buyer and increase his sale, seller use this terminology "Discount" . Discount is the difference of Marked Price and Selling Price
Or we can write it in a Mathematical formula:
Discount = Marked Price  Selling Price
Example 1 : Shirt whose marked price is $20 is sold at $18. Find the discount ?
Solution: As per the given question:
Marked Price = $ 20
Selling Price = $18
Apply formula of Discount (as explained above) and we get:
Discount = Marked Price  Selling Price
Put values of marked price and selling price from above and we get:
Discount = $20  $18
Solve the subtraction expression and we get:
= $2
Hence, shirt is sold at a discount of $2.
Find Marked price when selling price and discount is given:
For solution under this situation, we use the same formula; only difference is in calculation. This is explained with the help of example 2:
Example 2: Shop keeper gave discount of $1 and sold a book at $10. Find the marked price of the book ?
Solution: As per the given question:
Discount on book = $1
Selling Price of book = $10
Apply the same formula of discount:
Discount = Marked Price  Selling Price
Put values of marked price and discount from above and we get:
$1 = marked price  $10
Add $10 on both side and we get:
$11 = marked price
Or we can write it as:
Marked price = $11
Hence, marked price of shirt is $11
Find Selling price when marked price and discount is given ?
For solution under this situation, we use the same formula only difference is in calculation. This is explained with the help of example 3:
Example 3: Shop keeper sold a toy at discount of $5. Marked price of toy was $25. Find the selling price of toy ?
Solution: As per the given question:
Discount on toy = $5
Marked Price of toy = $25
Apply the same formula of discount:
Discount = Marked Price  Selling Price
Put values of marked price and discount from above and we get:
$5 = $25  selling price
Transpose and rearrange the above equation and we get:
Selling price = $25  $5
Solve the subtraction expression and we get:
Selling price = $20
Hence, toy was sold at $20
