The formula given below can be used to get percent of discount.
= (Amount of discount / Marked price) x 100 %
And also, list price or marked price is the one attached to the article before the discount made is called as marked price (or) list price of the article.
To find discount amount, we have to subtract selling price from the list or marked price.
Let us look at some examples to understand how to find percent of discount on a sale.
Example 1 :
A bicycle marked at $1500 is sold for $1350. What is the percentage of discount?
Given : Marked Price = $1500, Selling Price = $1350
Amount of discount = Marked Price – Selling Price
= 1500 – 1350
Discount for $1500 = $150
Percent of discount = (150/1500) ⋅ 100
= (1/10) ⋅ 100
Percentage of discount = 10%.
Example 2 :
The list price of a frock is $220. A discount of 20% on sales is announced. What is the amount of discount on it and its selling price?
Given : List (Marked) Price of the frock = $220,
Rate of discount = 20%
Amount of discount = (20/100) ⋅ 220
Selling Price of the frock = Marked Price – Discount
= 220 – 44
Example 3 :
A toy is on sale for 40% off. If the original price was $40, what is the new sales price?
Marked price = $40
Discount percent = 40%
Discount amount = 40% of 40
= (40/100) ⋅ 40
By subtracting the discount amount from marked price, we may get the sale price.
Sale price = 40 - 16
Example 4 :
After serious negotiating you got $25 discount on a pair of sneakers. If the original price of the sneakers was $125, what percentage discount did you get?
Discount amount = $25
Original price of the sneaker = $ 125
= (Amount of discount / Original price) ⋅ 100
= (25/125) ⋅ 100
So, the percent of discount we get is 20%.
Example 5 :
If you buy 2 pens and you get a 50% discount on the second pen. If 1 pen costs $2.30, how much will 2 pens cost you?
Cost of 1 pen = $2.30
Discount for the second pen = 50%
Discount amount for the second pen = 50% of 2.30
= (50/100) ⋅ 2.30
Cost price of 2 pens = 2.30 + 1.15
= $ 3.45
