If a seller gives a discount of 15% on retail price, she still makes a profit of 2%

If a seller gives a discount of 15% on retail price, she still makes a profit of 2%. Which of the following ensures that she makes a profit of 20%?

  1. Give a discount of 5% on retail price
  2. Give a discount of 2% on retail price
  3. Increase the retail price by 2%
  4. Sell at retail price

Answer

Let the retail price be 100.

Discount = 15

Selling price = 85

Cost price = 85/1.02 = 500/6

In order to make a profit of 20%, the selling price = 500/6 × 1.2 = 100

The seller must sell at the retail price.

The correct option is D.
