Show Answer

Answer:

Correct Answer: C

Solution:

  • Selling price after first discount $ =3200-\frac{10}{100}\times 3200 $ $ =3200-320=2880 $ Let second discount be x%. Selling price after second discount $ 2448=2880-\frac{x}{100}\times 2880 $

$ \Rightarrow $ $ \frac{x\times 2880}{100}=2880-2448 $

$ \Rightarrow $ $ x=\frac{432\times 100}{2880}=\frac{30}{2}=15 $ %
