Explanation

Simple Interest = (Principal * Rate * Time) / 100. SI = (1 * 5 * 4) / 100 = 20 / 100 = 0.2.

AI explanation

Using the simple interest formula where interest equals Principal times Rate times Time divided by 100, we substitute the given values to get 1 times 5 times 4 divided by 100. Multiplying the numerators gives 20, and dividing by 100 gives Rs. 0.2.
