A dealer gives a 20% discount on the marked price of a book. If the selling price of the book is Rs. 840, what is its marked price?
Show answer & explanation
Correct answer: C
Explanation
Given:
Discount = 20%
Selling Price = ₹840
According to the formula:
Selling Price = Marked Price × (100 − Discount)% / 100
840 = MP × 80/100
MP = 840 × 100 / 80
MP = ₹1050
