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?

Answer is (b).

Discount = Marked Price – Selling Price. Let the Marked Price of 10 articles = Rs. 100.

So, Marked Price of 8 articles = Rs. 80. (so each was marked at Rs.10)

So, as per the question, Rakesh purchased 10 mobile phones for Rs. 80

So, the selling price of 10 mobile phones = Rs. 80 (so each bought at Rs.8)

The discount is 2 rupees on 10 which is 20%.
