A merchant was selling an item at a certain price, then marked it down 20% for spring sale. During the summer, he marked the item down another 20% from its spring price. If the item was sold at the summer price, what percent of the original price did it sell for?

Correct Answer: 64%
Let the original price of the item was Tk. 100 Discount offered for spring sale = 20% Therefore, the selling price of the item in the spring = 100 - 20 = 80 tk The merchant gives another 20% discount on this for summer season Therefore, the selling price in the summer season = 80 - 80 × 20/100                                                                                     = 80 - 16 = 64 tk Now, selling price/Original price = 64/100 = 64% Therefore, the selling price is 64% of the original price.
