The selling prices of two articles are equal. If the first article is sold at a profit of 20% and the second article is sold at a loss of 20%, what will be the overall loss percentage?

4%

In this type of questions where the selling price is same and profit and the loss is also same then the seller always bears loss and is given by = \(\frac{x × x}{100}\)

x = 20%

Overall loss% = = \(\frac{20 × 20}{100}\) = 4%
