If the cost price of 70 articles is equal to the selling price of 40 articles, what will be the profit percentage?
Answer & explanation
Correct answer: option 1
The cost price of 70 articles = selling price of 40 articles
\(\frac{CP}{SP}\) = \(\frac{40}{70}\)
Profit% = (70 - 40) × \(\frac{100}{40}\) = 75%
