Explanation:

- Calculate the rate of simple interest for the first condition.

- Initial amount (P1) = Rs4,300

- Final amount (A1) = Rs4,644

- Time = 2 years

- Interest = A1 - P1 = Rs344

- Use simple interest formula: Interest = P1 * Rate * Time/100

- Solve for Rate: 344 = 4300 * Rate * 2/100 results in Rate = 4%

- Use the same rate for the second condition to find the principal.

- Final amount (A2) = Rs10,104

- Time = 5 years

- Use the formula: A2 = Principal (P2) * (1 + Rate * Time/100)

- Substitute the Rate (4%) and solve for P2:

- 10,104 = P2 * (1 + 4 * 5/100)

- P2 = 10,104 / 1.2 = Rs8,420

- Check against options.

- Option 2: Rs8,420 is a match.
