Q. A store offers a 30% discount on a jacket that originally costs $80. What is the sale price of the jacket?

A. $56
B. $60
C. $54
D. $50

Solution

Discount = 30% of 80 = (30/100) * 80 = 24. Sale price = 80 - 24 = $56.

Correct Answer: A — $56

Q. A store offers a discount of 15% on a jacket that costs $120. What is the final price after discount?

A. $90
B. $100
C. $105
D. $110

Solution

Discount = 15% of 120 = 0.15 * 120 = $18. Final Price = Cost - Discount = 120 - 18 = $102.

Correct Answer: B — $100

Q. A store offers a discount of 25% on a product. If the selling price is $75, what was the original price?

A. $100
B. $90
C. $80
D. $70

Solution

Let the original price be x. After a 25% discount, the selling price is 0.75x. Setting this equal to $75 gives 0.75x = $75, so x = $75 / 0.75 = $100.

Correct Answer: A — $100

Q. A store offers a discount of 25% on a shirt that costs $40. What is the final price after the discount? (2023)

A. $30
B. $35
C. $25

Solution

Discount = 25% of $40 = $10. Final price = $40 - $10 = $30.

Correct Answer: A — $30

Q. A store offers a discount of 25% on a shirt that costs $40. What is the final price of the shirt after the discount?

A. $30
B. $25
C. $35

Correct Answer: A — $30

Q. A store sells a laptop for $800 after applying a discount of 20%. What was the marked price?

A. $1000
B. $960
C. $850
D. $900

Solution

Let the marked price be x. After a 20% discount, the selling price is 0.80x = $800. Therefore, x = $800 / 0.80 = $1000.

Correct Answer: A — $1000

Q. A store sells a laptop for $800 after applying a discount of 20%. What was the original price of the laptop?

A. $1000
B. $960
C. $800
D. $840

Solution

Let the original price be x. Selling Price = x - 20% of x = 0.8x. Thus, 0.8x = 800, so x = 1000.

Correct Answer: A — $1000

Q. A store sells a laptop for $800 after applying a discount of 20%. What was the original price?

A. $900
B. $1000
C. $1100
D. $1200

Solution

Let the original price be x. Selling Price = x - 0.20x = 0.80x. So, 0.80x = 800. Therefore, x = 800 / 0.80 = 1000.

Correct Answer: B — $1000

Q. A store sells a shirt for $40 after a 10% increase in price. What was the original price?

A. $36
B. $32
C. $38
D. $34

Solution

Let the original price be x. Then, x + 0.1x = 40, so 1.1x = 40, thus x = 40/1.1 = $36.36.

Correct Answer: A — $36
