A television set has a marked price of ₹20,000. It is sold after two successive discounts. If the first discount is 15% and the final selling price is ₹15,300, what is the percentage of the second discount?

A10%

B12%

C14%

D15%

Answer:

A. 10%

Read Explanation:

Marked Price = ₹20,000

First discount = 15%

Price after first discount:

20000×8510020000 \times \frac{85}{100} = ₹17,000

The final selling price is ₹15,300.

Let the second discount be (x%).

17000(1x100)=1530017000\left(1-\frac{x}{100}\right)=15300


1x100=1530017000=0.91-\frac{x}{100}=\frac{15300}{17000}=0.9
x100=10.9=0.1\frac{x}{100}=1-0.9=0.1

x=10

Answer:

10%\boxed{10\%}
