The simple and compound interest that can be earned in two years at the same rate is ₹ 4,000/- and ₹ 4,180/- respectively. What is the rate(% per annum) of interest?

18% per annum

4.5% per annum

9% per annum

12% per annum

9% per annum

Shortcut Method:
When the simple interest and compound interest is given for two years, rate of interest (r%) is given by:
$C . I . = S . I . [1 + \frac{R}{200}]$
$\Rightarrow 4180 = 4000 [1 + \frac{r}{200}] \Rightarrow \frac{418}{400} = 1 + \frac{r}{200} \Rightarrow \frac{r}{200} = \frac{418}{400} - 1 \Rightarrow \frac{r}{200} = \frac{18}{400} \Rightarrow r = 9 %$
