Step 1: Understanding the Concept:
When equal amounts are withdrawn periodically, the "Average Period" method is used to calculate interest on total drawings.
Key Formula or Approach:
The formula for Average Period is:
\[ \text{Average Period} = \frac{\text{Months left after first drawing} + \text{Months left after last drawing}}{2} \]
Step 2: Detailed Explanation:
Assuming a financial year of 12 months:
1. The first drawing is at the beginning of the first quarter (e.g., April 1st). Months left = 12.
2. The last drawing is at the beginning of the last quarter (e.g., January 1st). Months left = 3.
Applying the formula:
\[ \text{Average Period} = \frac{12 + 3}{2} = \frac{15}{2} = 7.5 \text{ months} \]
Step 3: Final Answer:
Interest on total drawings will be calculated for 7.5 months.
