Solution

✅ Correct Option: 3

M draws Rs. 20,000 per month at the beginning of each month for 12 months.

Total drawings for the year = Rs. 20,000 × 12 = Rs. 2,40,000


Since drawings are made at the beginning of each month, each drawing earns interest for different periods:

  • January drawing → interest for 12 months
  • February drawing → interest for 11 months
  • March drawing → interest for 10 months
  • ... and so on
  • December drawing → interest for 1 month

For equal monthly drawings at the beginning of each month, the average time period = 6.5 months

This is calculated as: (12+11+10+...+1)÷12=78÷12=6.5(12 + 11 + 10 + ... + 1) ÷ 12 = 78 ÷ 12 = 6.5 months


Interest on drawings = Total Drawings × Rate × Average Period12\frac{\text{Average Period}}{12}

Interest = 2,40,000 × 12100\frac{12}{100} × 6.512\frac{6.5}{12}

Interest = 2,40,000 × 0.065

Interest = Rs. 15,600

Note: If drawings were made at the end of each month, the average period would be 5.5 months instead of 6.5 months.
