Calculate interest on drawing if Ram withdrew Rs. 3,000 per month at the beginning of each month for the whole year, if interest on drawing is charged @ 9 % per annum.
Solution
Since Ram withdrew Rs. 3,000 at the beginning of each month for the whole year, we need to calculate interest on these periodic drawings.
Total Drawings = Rs. 3,000 × 12 = Rs. 36,000
When equal amounts are withdrawn at the beginning of each month, the formula for interest on drawings is:
The "+1" is added because drawings are made at the beginning of each month (if withdrawn at the end, we would use the formula without +1).
Time Period = 12 months (whole year)
Substituting the values:
The average period for which drawings remain with Ram is 6.5 months (13/2 months), since the first drawing stays for 12 months and the last for 1 month.
Interest on Drawings = Rs. 1,755
