A bookstore buys 2,000 books for ₹180 each. They offer a "Buy 4, Get 1 Free" scheme but sell at the marked price of ₹225 per book. What is their effective profit percentage per book sold (after adjusting for the free books)?
Show answer & explanation
Correct answer: A
Explanation
Cost Price (CP) = ₹180 per book
Selling Price of 5 books = 4 × 225 = ₹900
Total Cost Price of 5 books = 5 × 180 = ₹900
Profit = 900 − 900 = ₹0
Profit Percentage = (0 / 900) × 100 = 0%
