In how much time will a sum of Rs 1600 amount to Rs 1852.20 at 5% per annum compound interest?

Explanation

To find the time it takes for a sum of Rs. 1600 to amount to Rs. 1852.20 at a compound interest rate of 5% per annum, we can use the formula for compound interest:

\[ A = P \left(1 + \frac{r}{100}\right)^t \]

Where:
- \( A \) = Amount after time \( t \)
- \( P \) = Principal amount (initial sum)
- \( r \) = Rate of interest per annum
