B Correct answer
Explanation

Time = 3 years 4 months = 3 + 4/12 = 3.33 years = 10/3 years. Simple Interest = (P * R * T) / 100 = (750 * 10 * 10/3) / 100 = 250. Amount = Principal + Interest = 750 + 250 = 1000.

AI explanation

Convert the time of 3 years and 4 months into a mixed fraction, which is 3 plus one-third, equaling 10 divided by 3 years. Using the formula for Simple Interest, SI equals 750 times 10 times 10 divided by 3 times 100, yielding Rs. 250. The total amount is the principal plus the interest, calculated as 750 plus 250, which equals Rs. 1,000.
