Option(2) is the correct answer.
Given,
Initial amount (P) = Rs. 5500
Rate of interest(r) = 15%
Time(t) = 2 years
Interest is compounded every 8 months (n = 8)
To Find,
The interest = ?
Solution,
Interest is compounded every 8 months = 12/8 per year
Interest is compounded for 2 years = 2(12/8) = 3 times in 2 years
Rate of interest compounded every 8 months = 15*(8/12) = 10%
From the formula of Compound interest,
Therefore, the final amount after 2 years will be Rs. 7320.5
Amount of Interest = A - P
Amount of Interest = 7320.5 - 5500
Amount of Interest = Rs. 1820.5
Hence, the compound interest on a sum of 5,500 at 15% p.a. for 2 years, when the interest is compounded 8 monthly, is Rs. 1820.5.
