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:

A retailer buys a used laptop for ₹22,500.

Actual cost price = 22500

His overhead expenses are ₹1,500.

cost price after adding expenses (final cost price) = 22500+1500 = 24000

He sells the laptop for ₹30,000.

Profit percentage = $$\frac{\left(selling\ price\ -\cos t\ price\ after\ adding\ \exp enses\right)}{\cos t\ price\ after\ adding\ \exp enses}\times100$$

= $$\frac{\left(30000\ -24000\right)}{24000}\times100$$

= $$\frac{6000}{24000}\times100$$

= $$\frac{1}{4}\times100$$

= 25%
