A retailer buys a used laptop for ₹22,500. His overhead expenses are ₹1,500. He sells the laptop for ₹30,000. The profit percentage of the retailer is:

25%

The cost price of the laptop = 22,500

Over head expenses = 1500

Then the actual cost price of the laptop = 22500 + 1500 = 24000

Selling price of the laptop = 30000

Profit% = ( 30000 - 24000 ) × \(\frac{100}{24000}\) = 25%
