Explanation:

- To solve this problem, first understand that the amount becomes a fraction of itself in two years due to simple interest.

- This implies a certain percentage is added over the initial principal each year.

- The formula for simple interest is: $$\text{Interest}=\frac{\text{Principal}\times \text{Rate}\times \text{Time}}{100}$$

- Over two years, if the sum becomes a certain fraction, you calculate the rate by dividing the added fraction by 2.

Here's the evaluation of options:

- Option 1: ?? ??/?? %

- Option 2: ?? ??/’?? %

- Option 3: ?? ??/?? %

- Option 4: ?? ??/?? %

- Since details are missing, we can't calculate the exact rate. Assuming usual fractions, the process involves basic arithmetic based on fractions becoming whole numbers due to added interest over time.

If you assumed option 3 based on some calculations or typical values:
