Calculation of Sale Price

To find the sale price of a dress marked at rupees 120 with a discount of 20 percent, we need to follow a few steps:

Step 1: Calculate the discount amount

The discount amount can be calculated by multiplying the original price of the dress by the discount percentage.

Discount amount = Original price * Discount percentage

In this case, the original price of the dress is rupees 120 and the discount percentage is 20 percent.

Discount amount = 120 * (20/100) = 24 rupees

Step 2: Subtract the discount amount from the original price

To find the sale price, we need to subtract the discount amount from the original price.

Sale price = Original price - Discount amount

Sale price = 120 - 24 = 96 rupees

Therefore, the sale price of the dress after a 20 percent discount is rupees 96.

Summary:

- The original price of the dress is rupees 120.
- The discount percentage is 20 percent.
- The discount amount is calculated by multiplying the original price by the discount percentage, which results in 24 rupees.
- Subtracting the discount amount from the original price gives us the sale price of the dress, which is 96 rupees.
