Answer 1

Answer:

Selling price =Rs. 550.8 or 551

Step-by-step explanation:

Since two successive discounts are given

Instead of solving one after other

We can write

$\frac{100 - 15}{100} \times \frac{100 - 10}{100} \times 720 \\ \frac{85}{100} \times \frac{90}{100} \times 720 \\ \frac{17}{20} \times \frac{9}{10} \times 720 \\ on \: solving \\ = 550.8$
