Correct Answer: 12.8%
Solution :
Given:
Cost Price = INR $24,000$
Marked Price = INR $30,000$
Profit = $9$%
Selling Price = $\frac{109}{100}×24000=26160$
Discount = Marked Price – Selling Price
⇒ Discount = $30000 - 26160$ = INR $3840$
Discount percentage $=\frac{3840}{30000}×100=12.8$%
Hence, the correct answer is 12.8%.
