Step-by-step explanation:

Let the profit be x

10% profit : 10x

Assume cost price is 100x

Selling price is: 100x + 10x = 110x

110x = 330

x = 330 / 110

x = 3

10% profit = 10×3 = 30

Cost price= Selling price - profit

= 330 - 30

= 300

Cost price : 300

Verify:

10% of cost price: 10/100 × 300 = 30

Selling price: Cost price + 10% profit

300 + 30 = 330 Selling price as mentioned in question.
