A bookshop advertises: "Buy 4 books and get the 5th at 50% discount." If the marked price of each book is Rs. 480 and all books are priced the same, what is the effective percentage discount the customer receives on the total purchase?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 10%.
Normal cost for 5 books = 5 × 480 = 2400
Present cost = 4 × 480 + 0.5 × 480 = 1920 + 240 = 2160
Discount = 2400 – 2160 = 240
Discount percentage = (240/2400) × 100 = 10%
