Explanation

Simple Interest = (P * R * T) / 100. 810 = (P * 9 * 6) / 100. 810 = 54P / 100. P = 81000 / 54 = 1500.

AI explanation

Using the simple interest formula, Simple Interest = (Principal x Rate x Time) / 100, we substitute the known values to get 810 = (Principal x 9 x 6) / 100. Solving for the principal yields 81000 = 54 x Principal, which gives Principal = Rs. 1500.
