Answer:
Percentage profit = 11.3%
Step-by-step explanation:
<u>Given the following data;</u>
- Vat = 13% = 13/100 = 0.13
- Cost price = 10,000
- Selling price = Rs 12430
To calculate the profit percentage on the article;
First of all, we would determine the value-added (vat) tax levy;
Vat levy = 0.13 * 10000
Vat levy = Rs. 1300
Profit = selling price - cost price
Profit = 12430 - 10000
Profit = 2430
Profit after vat;
Profit after vat = Profit - Vat levy
Profit after vat = 2430 - 1300
Profit after vat = 1130
Next, we would calculate the profit percentage on the article;
Substituting the values into the formula, we have;
<em>Percentage profit = 11.3%</em>
