Correct Answer: INR 650


Solution : Given: Cost price = INR 450
Selling price = $\frac{100+\text{profit %}}{100}\times$ cost price
= $\frac{100+30}{100}\times450$
= $\frac{130}{100}\times450$
= 585
Selling price = $\frac{100-\text{discount %}}{100}\times$ mark price
⇒ $585 = \frac{100-10}{100}\times$ mark price
⇒ Mark price = $\frac{585\times100}{90}$
= 650
Hence, the correct answer is INR 650.
