C Correct answer
Explanation

Let the cost price of one article be CP and selling price be SP. Given 8 * CP = 10 * SP, so SP = 0.8 * CP. The loss is CP - SP = 0.2 * CP, which is a 20% loss.

AI explanation

Assume the cost price of one article is 10, making the cost price of 8 articles equal to 80. This equals the selling price of 10 articles, so the selling price of one article is 8. Using the loss percentage formula, loss percent equals loss divided by cost price multiplied by 100, which gives 2 divided by 10 multiplied by 100 to equal 20 percent. The result is 20 percent.
