Let the cost price of item = Rs.x
Therefore, Marked price of Item = \( \Large \frac{x \times \left(100+20\right) }{100}=Rs.\frac{6x}{5} \)
Then, selling price of item = \( \Large \frac{6x}{5} \times \left(\frac{100-15}{100}\right)=\frac{6x \times 17}{5 \times 20} = Rs.\frac{102}{100}x \)
= Profit = \( \Large \left(\frac{102x}{100}-x\right) = Rs.\frac{2}{100}x \)
Gain per cent = \( \Large \frac{\frac{2x}{100} \times 100\%}{x} \) = 2%
