Explanation:

To determine how much Aman has to pay after 3 years, we can use the compound interest formula:

$$A=P\times (1+\frac{r}{100}{)}^n$$

Where:

- $A$ is the amount to be paid back.

- $P$ is the principal amount, which is Rs50,000.

- $r$ is the annual interest rate, which is 8%.

- $n$ is the number of years, which is 3.

Let's calculate step-by-step:

- Calculate the formula step-by-step:

- First, divide the rate by 100: $\frac{8}{100}=0.08$

- Then, add one to the rate: $1+0.08=1.08$

- Raise to the power of 3: $(1.08{)}^3˜1.2597$

- Multiply by the principal: $50,000\times 1.2597˜62,985$

- Options Review:

- Option 1, Rs62,517: Less than the actual calculated value. Incorrect.

- Option 2, Rs62,871: Close to actual value but slightly less. Incorrect.

- Option 3, Rs62,986: Matches computed value.

- Option 4, Rs62,000: Much less than actual value. Incorrect.

The correct amount Aman needs to pay is Option 3, Rs62,986.

Therefore, “”.
