Rakesh had money to buy 8 mobile handsets of a specific company. But the retailer offered very good discount on that particular handset. Rakesh could buy 10 mobile handsets with the amount he had. What was the discount the retailer offered?
Sale price of 10 handsets = Marked price of 8 handsets
Sale price of 1 handset = Marked price of 8/10 handsets
Discount % = (Marked price - Sales price)/(Marked price) × 100
Discount % = (1 - 8/10) × 100
Discount % = 20%
The correct option is B.
