It is given that the principal amount is Rs 500.
Rate of interest = 10% per annum.
Time = 10 years.
Since the interest is compounded annually, the amount is given by the formula:
\[ A = P\left(1 + \frac{R}{100}\right)^n \]
Substituting the given values:
\[ A = 500\left(1 + \frac{10}{100}\right)^{10} \]
\[ A = 500(1.1)^{10} \]
\[ A = 500 \times 2.593742 \]
\[ A \approx 1296.87 \]
Thus, Rs 500 will amount to approximately Rs 1296.87 after 10 years.
