A man buys 9 identical articles for a total of ₹16. If he sells each of them for ₹2.8, then his profit percentage will be ______%.
57.5
Cost price of 9 articles = ₹16, so cost price of 1 article = \(\dfrac{16}{9}\).
Selling price of 1 article = ₹2.8 = \(\dfrac{14}{5}\).
Profit on 1 article = \(\dfrac{14}{5}-\dfrac{16}{9}=\dfrac{126-80}{45}=\dfrac{46}{45}\).
Profit % = \(\dfrac{\text{Profit}}{\text{CP}}\times100=\dfrac{46/45}{16/9}\times100\).
= \(\dfrac{46}{45}\times\dfrac{9}{16}\times100=\dfrac{46}{80}\times100=57.5\).
Hence, the profit percentage is 57.5%.
