Explanation:

Let's calculate:

- Scheme A:

- Principal (P) is invested at 20% compound interest for 2 years.

- Final amount = $P\times (1+0.20{)}^2=P\times 1.44$

- Interest from Scheme A = $1.44P-P=0.44P$

- Scheme B:

- This interest (0.44P) is reinvested for 2 years at 15% simple interest.

- Final amount from Scheme B = $0.44P\times (1+2\times 0.15)=0.44P\times 1.30=0.572P$

- Given final amount from Scheme B is Rs 1430.

- Equation:

- $0.572P=1430$

- Solving for P: $P=\frac{1430}{0.572}\approx 2500$

- Correct Option:

- Option 2: Rs 2500

So, Option 2: Rs 2500 is correct. .
