The cost price of 30 articles is equal to the selling price of 25 articles. What is the profit percentage in this transaction?
Answer & explanation
Correct answer: option 2
CP30 = SP25
So, we can say that:
\(\frac{ CP}{SP }\) = \(\frac{25 }{ 30}\)
\(\frac{ CP}{SP }\) = \(\frac{5 }{ 6}\)
Profit% = \(\frac{1 }{ 5}\) x 100 = 20%
