A Correct answer
Explanation

Interest on drawings for a fixed amount withdrawn in the middle of every month is calculated for 12 months. Formula: Interest = (Total Drawings * Rate * 6/12). 4800 = (x * 12 * 0.08 * 0.5), so 4800 = 0.48x, giving x = 10,000.

AI explanation

When a fixed amount is withdrawn in the middle of every month, the average period is calculated as 6.5 months, or 6.5/12 of a year. Using the interest on drawings formula, Interest = Total Drawings * Rate * Average Period, we have 4800 = Total Drawings * (8/100) * (6.5/12). Solving this gives Total Drawings = 120000. Dividing this by 12 months yields a monthly drawing amount of Rs. 10,000.
