Common percentage word problem types

Type 1: Finding a percentage of a number

"A store offers 30% off a $150 jacket. What is the discount amount?"

Discount = 150 × 30 ÷ 100 = $45

Sale price = $150 − $45 = $105

Type 2: Finding what percentage one number is of another

"A student scored 54 out of 80 on a test. What percentage did they score?"

Score % = (54 ÷ 80) × 100 = 67.5%

Type 3: Percentage increase / decrease

"A house was worth $400,000 and is now worth $460,000. What is the percentage increase?"

Increase = ((460,000 − 400,000) ÷ 400,000) × 100 = 15%

"After a 20% discount, a TV costs $320. What was the original price?"
