Question

Lemons were bought at 4 for Rs 3 and sold at 5 for Rs 4 . What was the gain or loss per cent?

Answer 1

Cost of one lemon: $\left(\frac{3}{4}\right)Rs$

Selling price of one lemon $\left(\frac{4}{5}\right)Rs$

$\therefore$ Profit percentage $=\left(\frac{\left(\frac{4}{5}\right)-\left(\frac{3}{4}\right)}{\left(\frac{3}{4}\right)}\right)\cdot 100=\left(\frac{16-15}{20}\right)\cdot \left(\frac{4}{3}\right)\cdot 100\%=6.67\%$
