Calculate the total amount when ₹4000 is invested at 10% compound interest per annum, compounded annually for 2 years.
₹4840
For compound interest compounded annually, amount \(A = P\left(1 + \frac{R}{100}\right)^n\).
Here \(P = 4000\), \(R = 10\%\) and \(n = 2\) years.
\(A = 4000\left(1 + \frac{10}{100}\right)^2 = 4000 \times (1.1)^2 = 4000 \times 1.21\).
\(A = 4840\).
Hence, the total amount is ₹4840.
