Rakesh had money to buy 8 mobile handsets of a specific company

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?

  1. 15%
  2. 20%
  3. 25%
  4. 30%

Answer

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.
