D Correct answer
Explanation

Simple Interest = (P * R * T) / 100. 3840 = (P * 10 * 3) / 100, so P = 12800. The amount is Principal + Interest = 12800 + 3840 = 16640.

AI explanation

Using the simple interest formula (P * R * T) / 100, the principal sum is calculated as (3840 * 100) / (10 * 3), which equals Rs. 12800. The total amount received at the end of 3 years is the sum of the principal and the interest, so Rs. 12800 + Rs. 3840 equals Rs. 16640.
