If 60 percent of total articles are sold at a loss of 20 percent and remaining articles are sold at a profit of 5 percent, then what will be the overall loss percentage?

10 percent

Let the total quantity = 100

60% = 60 sold at 20% loss

and 40% = 40 sold at 5% profit

60%       60                    48

40%       40                    42

           ——————————————

            100                  90               

Loss = 100 - 90 = 10

Loss% = \(\frac{10 × 100}{100}\) = 10%
