12 books, each of Rs. 360, are sold at Rs. 3600. What is the percentage of the discount given?
Show answer & explanation
Correct answer: A
Explanation
Given:
Marked price per book = ₹360
Number of books = 12
Total selling price = ₹3600
Total marked price = 12 × 360 = 4320
Discount = 4320 − 3600 = 720
Discount percentage = (720 / 4320) × 100 = 16.67%
