Question

By selling 20 articles, a person gains CP of 5 articles. Find the profit% incurred by him.

Answer 1

Let the S.P of one article be $S$ and Cost price of one article be $C$

Total Sale price = $20S$

Total Cost Price = $20C$

So,Profit = $20S-20C=5C$

Thus $\frac{S}{C}=\frac{4}{3}$

So Profit %=$33.33$%
