When the price of a computer was reduced by 20%, the sale increased by 60%. What was the increase in total revenue?

Solution

Let original price = 100 and quantity sold = 100. Original revenue = 100 × 100 = 10,000. New price = 80, new sales = 160. New revenue = 80 × 160 = 12,800. Increase in revenue = (12,800 − 10,000)/10,000 × 100 = 28%.
