Question

A shopkeeper sold an article for Rs. 24 and
gained as much percent as the cost price of
the article. For finding the cost price of the
article, obtain a quadratic equation.

Answer 1

Let the cost of the article = Rs x

Profit percent = x %

Cost of an article is always positive.

∴ x = Rs. 20

Thus, the gain percent on the article is 20%.
