Explanation:

- We have two fixed deposits for a total amount of Rs. 16500.

- The deposits earn Simple Interest at rates of 10% and 12% over 2 years.

- Total interest from both deposits is Rs. 3620.

- Let's assume the amount in the 12% scheme is Rs. x.

- Therefore, the amount in the 10% scheme will be Rs. (16500 - x).

- Interest from the 12% scheme: $\frac{x\times 12\times 2}{100}=0.24x$.

- Interest from the 10% scheme: $\frac{(16500-x)\times 10\times 2}{100}=0.2(16500-x)$.

- Total interest equation: $0.24x+0.2(16500-x)=3620$.

- Simplifying the equation: $0.24x+3300-0.2x=3620$.

- $0.04x=320$.

- Solve for x: $x=8000$.

Option 5: Rs. 8000
