Saloni buys a book for Rs. 275 and sells it at a profit of Rs. 55. Find the selling price.

Given: Cost price of the book = Rs. 275

Profit = Rs. 55

Let the selling price be x.

By using the formula,

Profit = Selling price − Cost price

⇒ 55 = x − 275

⇒ x = 55 + 275

⇒ x = 330

Hence, the selling price of the book is Rs. 330.
