If $\text{Rs. }1,500$ is invested at $5\%$ per annum compounded annually, what will be the total amount after $2\text{ years}$?

The formula for the total amount ($A$) under compound interest is:
$$A=P{\left(1+\frac{R}{100}\right)}^n$$

Given:

* Principal ($P$) = $\text{Rs. }1,500$
* Rate ($R$) = $5\%$
* Time ($n$) = $2\text{ years}$

Substitute the values into the formula:

$$A=1500{\left(1+\frac{5}{100}\right)}^2$$

$$A=1500{\left(1+0.05\right)}^2$$

$$A=1500{\left(1.05\right)}^2$$

$$A=1500\times 1.1025=\text{Rs. }1,653.75$$

Therefore, the amount after $2\text{ years}$ will be $\text{Rs. }1,653.75$.
