₹$8,600$ / ₹$8,600$
Correct Answer: ₹$9,600$ / ₹$9,600$
For $2$ years, $CI - SI = P\left(\frac{r}{100}\right)^2$. So $P \times (0.10)^2 = 96$, giving $P = \frac{96}{0.01} =$ ₹$9,600$. / $2$ वर्षों के लिए, $CI - SI = P\left(\frac{r}{100}\right)^2$। अतः $P \times (0.10)^2 = 96$, जिससे $P = \frac{96}{0.01} =$ ₹$9,600$।
