C Correct answer
Explanation

Ratio of Amount (Principal) to Interest = 10:3. Interest = (P * R * T) / 100. 3 = (10 * 6 * T) / 100. 3 = 0.6 * T. T = 3 / 0.6 = 5 years.

AI explanation

The ratio of the principal to the simple interest is given as 10:3, meaning the interest equals 3/10 of the principal. Using the simple interest formula T = (100 * SI) / (P * R), we substitute SI/P with 3/10 to get T = 100 * (3/10) / 6. This simplifies to 30 / 6, which gives a time period of 5 years.
