If selling price of 80 articles is equal to the cost price of 100 articles, then find the gain percentage.
Answer & explanation
Correct answer: option 2
Selling price of 80 articles = The cost price of 100 articles
\(\frac{SP}{CP}\) = \(\frac{100}{80}\)
Profit = 100 - 80 = 20
Profit% = 20 × \(\frac{100}{80}\) = 25%
