Correct Answer: 12% / 12%
For 2 years, difference $= P\left(\frac{r}{100}\right)^2$: $180 = 12500\times\frac{r^2}{10000} \Rightarrow r^2 = 144 \Rightarrow r = 12\%$. / 2 वर्षों के लिए अंतर $= P\left(\frac{r}{100}\right)^2$: $180 = 12500\times\frac{r^2}{10000} \Rightarrow r^2 = 144 \Rightarrow r = 12\%$।
