**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.
