    A person invests some amount at 6% p.a. at simple interest and gets Rs.900 as interest after 3 years. If the interest is compounded annually, then what extra interest he would obtain on the same amount at the same rate for the same period of time?

    A)  \[Rs.38.13\]                  

    B)  \[Rs.25.33\]

    C)  \[Rs.55.63\]    

    D)  \[Rs.35.30\]

    Correct Answer: C

    Solution :

     \[P=\frac{900\times 100}{3\times 6}=Rs.5,000\] Let d be the difference between CI and SI then, \[d=P\times \frac{{{r}^{2}}}{100\times 100}\frac{(300+r)}{100}\] \[=\frac{5000\times 36}{100\times 100}\times \frac{(300+6)}{100}\] \[=\frac{500\times 36\times 306}{100\times 100\times 100}=\]
