Two articles are bought at the same price. One is sold at 30% profit and the other is sold at 20% loss. Find the overall profit/loss percentage.
Assume that the cost price of each of the articles as Rs.100. So, the total cost price is Rs.200.
The first article is sold at a profit of 30%, which makes its selling price as Rs.130.
The second article is sold at a loss of 20%, which makes its selling price as Rs.80.Â
The total selling price is Rs.210, while the total cost price is Rs.200.
Hence, profit% = (10/200) * 100, which is 5%.
