Question : INR 12,000 is lent for one year at the rate of 15 % per annum, the interest being compounded annually. If the compounding of the interest is done half-yearly, then how much more interest will be obtained at the end of the one year on the same initial sum?

Option 2: INR 82.8

Option 3: INR 60.5

Option 4: INR 67.5

Team Careers360 24th Jan, 2024

Correct Answer: INR 67.5


Solution : Principal, $P = 12000$
Term, $n = 1$ year
Rate, $R = 15$%
When compounded half-yearly,
Compound Interest, CI = $P(1+\frac{R}{200})^{2n}-P$
= $12000 × (1+\frac{15}{200})^2 - 12000$
= $12000 × (\frac{215}{200})^2 - 12000$
= $12000 × (\frac{43}{40})^2 - 12000$
= $12000 × \frac{1849}{1600} -
