C Correct answer
Explanation

Simple Interest formula: SI = (P * R * T) / 100. 3822 = (18200 * 3 * T) / 100. 3822 = 546 * T. T = 3822 / 546 = 7.

AI explanation

Using the simple interest formula where Time equals Interest multiplied by 100 divided by the product of Principal and Rate, we substitute the given values. This gives Time as 3822 times 100 divided by the product of 18200 and 3, which simplifies to 382200 divided by 54600, resulting in 7 years.
