The difference between the simple interest and the compound interest on a certain amount at 9% per annum for two years is 162. What is the principal?

Show answer & explanation

Correct answer: C

Explanation

The correct answer is option 3 i.e. 20000.

The difference between SI and CI for two years = PR21002\frac{PR^2}{100^2}

So, P×921002=162\frac{P\times 9^2}{100^2}=162

⇒ P = 162 × (10000/81) = 20000

Therefore, the principal is 20000.
