    If the difference between the compound interest, compounded every six months, and the simple interest on a certain sum of money at the rate of 12% per annum for one year is Rs. 36, the sum is

    A) Rs. 10000         

    B) Rs. 12000

    C) Rs. 15000         

    D) Rs. 9000

    Correct Answer: A

    Solution :

    Sum \[=\frac{36\times 100\times 100}{6\times 6}=10000\] Note As the interest was compounded half yearly, we changed r to \[\frac{r}{2}\] and t to 2t.
