Team Careers360 · Accepted Answer

Correct Answer: INR 10,260

Solution : A successive discount of 5%, 10%, and 20% means that these discounts are applied one after another
For three successive discounts of 5%, 10%, and 20%,
Selling price = $\frac{100- ext{Discount}_1\%}{100}× \frac{100- ext{Discount}_2\%}{100}×\frac{100- ext{Discount}_3\%}{100}×$ marked price
⇒ Selling price $=\frac{100-5}{100}×\frac{100-10}{100}×\frac{100-20}{100}×15000$
⇒ Selling price $=\frac{95}{100}×\frac{90}{100}×\frac{80}{100}×15000$
⇒ Selling price $=10260$
Hence, the correct answer is INR 10,260.
