Explanation
II. Let C.P. $=₹x$. Then, M.P. $=130\%$ of ₹$x=₹\left(\frac{13x}{10}\right)$. I. Discount $=10\%$. S.P. $=90\%$ of ₹$\frac{13x}{10}=₹\left(\frac{90}{100}\times\frac{13x}{10}\right)=₹\left(\frac{117x}{100}\right)$. Profit $=₹\left(\frac{117x}{100}-x\right)=₹\frac{17x}{100}$. ∴ Profit\% $=\left(\frac{17x}{100}\times\frac{1}{x}\times 100\right)\%=17\%$.
