What is the rate of discount if a car that had a regular price of Tk. 30,00,000 is sold for Tk. 27,90,000?

A 7%

B 8%

C 9%

D None of these

Correct Answer: Option A

Discount amount = 30,00,000 - 27,90,000 tk

= 2,10,000 tk

Thus,

When original price is 30,00,000, discount is 2,10,000 tk

When original price is 100, discount is 2,10,000 * 100 / 30,00,000 tk

= 7 tk
