Explanation

Simple Interest = (P * R * T) / 100. 1240 = (P * 6 * 3) / 100. 1240 = 18P / 100. P = 124000 / 18 = 6888.88, which rounds to 6889.

AI explanation

Using the simple interest formula Principal = (Simple Interest * 100) / (Rate * Time), we substitute the given values. The principal equals (1240 * 100) / (6 * 3), which simplifies to 124000 / 18. This calculation gives the required investment amount of approximately 6889 rupees.
