As per the given data,

Selling price = Rs. 4500

Profit = 12.5%

Let us consider the cost price of the article be Rs. x

We know that profit% = (SP – CP)/CP × 100

⇒ 12.5 = (4500 – x)/x × 100

⇒ 12.5x = 450000 – 100x

⇒ 112.5 x = 450000

⇒ x = Rs. 4000

∴ Cost price = Rs. 4000

⇒ Profit = Selling price – cost price = 4500 – 4000 = Rs. 500
