Let us calculate the compound interest and amount on ₹1600 for years at the rate of 10% compound interest per

annum compounded at the interval of 6 months.

We know that if the rate of compound interest is r% per annum and the interest is compounded half yearly, the number of phase of compound interest in a year is 2, then the amount for n years


From given, p = ₹1600, r = 10 and n = year years


∴ Amount for year







= ₹1852.2


∴ Compound interest for year = ₹1852.2 - ₹1600


= ₹252.2
