Explanation

Selling price = Cost Price + (Gain % * Cost Price) = 20 + (0.10 * 20) = 20 + 2 = 22.

AI explanation

Using the selling price formula, Selling Price = Cost Price * (1 + Gain%/100), we substitute the given values to get 20 * (1 + 10/100). This simplifies to 20 * 1.10, which equals 22. The selling price is Rs. 22.
