Explanation:

To find the simple interest on Rs 0000 (which seems like a typo, assuming principal is Rs 10000), we first need the rate of interest.

- ?291600 to ?314928 in 1 year on compound interest means growth is 7.9982%.

- For CI formula: A = P(1 + r/100)^n, r from above gives 7.9982%.

- For simple interest (SI), formula: SI = P * R * T/100.

- P = ?10000, R = 7.9982, T = 2 years. Calculate SI.

- SI = 10000 * 7.9982 * 2 / 100 = ?1600.
