What is the compound interest on ₹20,000 for 9 months at the rate of 4% per annum, when interest is compounded quarterly?

Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. ₹606.02

Formula used:

CI = P(1 + R/100)T - P

Where, CI = compound interest, P = principal, R = rate and T = time

Calculations:

Rate when compounded quaterly = R/4 = 4/4 = 1%

Time = 9 months or 3 years cycle

Using above equation;

⇒ CI = 20000(1 + 1/100)T - 20000

⇒ CI = 20606.02 - 20000

⇒ CI = 606.02
