We need to calculate interest on Arora's drawings when fixed amounts are withdrawn at the beginning of each quarter.
Step 1: Understand the drawings pattern.
- Amount withdrawn each quarter = ₹ 30,000
- Withdrawn at the beginning of each quarter
- Starting from 1st October, 2024
- Year ended 31st March, 2025
So the quarters and dates are:
- Quarter 1: 1st October, 2024 (beginning of Oct-Dec quarter)
- Quarter 2: 1st January, 2025 (beginning of Jan-Mar quarter)
Step 2: Determine the period for which each withdrawal remains outstanding.
Interest is charged for the period from the date of withdrawal to the end of the accounting year (31st March, 2025).
- Withdrawal on 1st Oct, 2024: Period = 6 months (Oct to Mar)
- Withdrawal on 1st Jan, 2025: Period = 3 months (Jan to Mar)
Step 3: Calculate interest using product method.
\[
\text{Interest} = \text{Total of Products} \times \frac{\text{Rate}}{100} \times \frac{1}{12}
\]
Alternatively, calculate interest for each withdrawal:
For ₹ 30,000 for 6 months:
\[
\text{Interest} = 30,000 \times \frac{12}{100} \times \frac{6}{12} = 30,000 \times 0.12 \times 0.5 = ₹ 1,800
\]
For ₹ 30,000 for 3 months:
\[
\text{Interest} = 30,000 \times \frac{12}{100} \times \frac{3}{12} = 30,000 \times 0.12 \times 0.25 = ₹ 900
\]
Step 4: Total interest.
\[
\text{Total Interest} = 1,800 + 900 = ₹ 2,700
\]
Step 5: Alternative method using average period.
For drawings at the beginning of each quarter, the average period = \(\frac{6 + 3}{2} = 4.5\) months? Actually, for 2 quarters, the formula is:
Average period = \(\frac{\text{Total months for all drawings}}{\text{Number of drawings}}\)
= \(\frac{6 + 3}{2} = 4.5\) months
Total drawings = ₹ 60,000
\[
\text{Interest} = 60,000 \times \frac{12}{100} \times \frac{4.5}{12} = 60,000 \times 0.12 \times 0.375 = ₹ 2,700
\]
Final Answer: (B) ₹ 2,700
