Explanation:

To solve the problem, we need to calculate the Simple Interest (SI) and Compound Interest (CI) and find their difference:

- Simple Interest (SI) Calculation:

- Formula: SI = P * R * T / 100

- For 3 years at 12%: SI = P * 12 * 3 / 100 = 0.36P

- Compound Interest (CI) Calculation:

- Formula: CI = P*(1 + R/100)^T - P

- For 2 years at 15%: CI = P*(1 + 15/100)^2 - P = P*(1.15)^2 - P = P*(1.3225 - 1) = 0.3225P

- Difference Between CI and SI:

- Difference = 0.36P - 0.3225P = 0.0375P

- Given this difference is Rs. 375, solve for P:

- 0.0375P = 375

- P = 375 / 0.0375 = 10000

- Therefore, the value of P is 10000.

- Correct Answer: Option: 1 - 10000

The correct answer is Option: 1 - 10000.
