C Correct answer
Explanation

Selling Price = Cost Price + Profit. 572 = CP + 0.30 * CP = 1.3 * CP. CP = 572 / 1.3 = 440.

AI explanation

The selling price is the cost price plus the profit, which translates to the formula Selling Price = Cost Price + 0.30 * Cost Price, meaning Selling Price is 130% of the Cost Price. So, 572 = 1.3 * Cost Price. Dividing 572 by 1.3 gives the cost price of 440 rupees.
