Question : What will a person get after 3 years at compound interest, when the principal is Rs. $S$ and the rate of interest is $2r$% per annum?
Option 1: Rs. $\frac{6Sr}{100}$
Option 2: Rs. $S(1+\frac{r}{100} )^{3}$
Option 3: Rs. $S( 1+\frac{r}{50} )^{3}$
Option 4: Rs. $3S( 1+\frac{r}{100} )^{3}$
Correct Answer: Rs. $S( 1+\frac{r}{50} )^{3}$
