Problem 1 :
A bicycle marked at $1500 is sold for $1350. What is the percentage of discount?
Solution :
Given : Marked Price is $1500, Selling Price is $1350.
Amount of discount = Marked Price – Selling Price
Amount of discount = 1500 – 1350
Amount of discount = $150
Discount for $1500 is $150.
Percent of discount = (150/1500) ⋅ 100
Percent of discount = (1/10) ⋅ 100
Percent of discount = 10%
So, percentage of discount is 10%.
Problem 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?
Solution :
Given : List (Marked) Price of the frock is $220,
Discount % = 20%
Amount of discount is
= (20 / 100) ⋅ 220
= $44
Selling Price :
= Marked Price – Discount
= 220 – 44
= $176
So, the selling price of the frock is $176.
Problem 3 :
A toy is on sale for 40% off. If the original price was $40, what is the new sale price?
Solution :
Given : Marked price is $40, Discount percent is 40%.
Discount amount = 40% of 40
Discount amount = (40/100) ⋅ 40
Discount amount = 16
By subtracting the discount amount from the original price, we will get the new sale price.
New sale price = 40 - 16
New sale price = $24
Problem 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?
Solution :
Given : Discount amount is $25, Original price is $125.
Discount percent :
= (Amount of discount / Original price) ⋅ 100
= (25/125) ⋅ 100
= 20%
So, the percent of discount i got is 20%.
Problem 5 :
If you buy 2 pens you get a 50% discount on the second pen. If 1 pen costs $2.30, how much will 2 pens cost you?
Solution :
Given : Cost of 1 pen is $2.30, discount for the second pen is 50%.
Discount amount for the second pen = 50% of 2.30
= (50/100) ⋅ 2.30
= 1.15
Price of the 1^{st} pen + Price of the 2^{nd} pen :
= 2.30 + 1.15
= $3.45
So, two pens will cost $3.45.
