Let CP of the goods = Rs.x.
Marked price of the goods
= \( \Large \frac{x \times \left(100+30\right) }{100} \)
= Rs. \( \Large \frac{13x}{10} \)
Now, SP of 'the goods = \( \Large \frac{13x}{10} \times \left(\frac{100-15}{100}\right) \)
= \( \Large \frac{13x}{10} \times \frac{85}{100}=Rs.\frac{21}{200}x \)
= Profit = \( \Large \left( \frac{221}{200}x- x \right) = Rs.\frac{21}{200}x \)
Hence, profit per cent = \( \Large \frac{\frac{221}{200}x}{x} \times 100\% \)
\( \Large \frac{2100}{200} \) = 10.5%
