Given parameters:
Marked price = Rs. 100
Selling price = Rs. 80
Unknown:
Discount rate = ?
Solution:
The price on the label of an article is the marked price;
Discount amount = Marked price - selling price
= Rs. 100 - Rs. 80
= Rs. 20
Discount rate = [tex]\frac{Discount }{Marked price } x 100[/tex]
Discount rate = [tex]\frac{20}{100}[/tex] x 100 = 20%
