- Simple interest (SI) for 5 years is 25% of the principal.

- This implies SI = 0.25P in 5 years, where P is the principal.

- Therefore, annual interest rate (R) is \( \frac{0.25P}{5} = 0.05P \) or 5%.

- We need to find the number of years when the interest equals the principal.

- Set equation: \( \text{SI} = \text{Principal} \)

- Given that SI for 5 years is 0.25P, we scale to full P: \( t \times 0.05P = P \)

- Solving for \( t \): \( t = \frac{P}{0.05P} = 20 \) years.

- Option 1: 20

- Option 2: 30

- Option 3: 25

- Option 4: 22
