Step 1: Compute interest on full capital for 6 months.
Tara’s capital = ₹ 4,00,000
Withdrawal date = 1st October, 2023
So, for the first 6 months (April to September), interest is calculated on full ₹ 4,00,000:
\[
\text{Interest} = \frac{4,00,000 \times 8 \times 6}{100 \times 12} = ₹ 16,000
\]
Step 2: Compute interest on reduced capital for next 6 months.
After withdrawal of ₹ 1,00,000, remaining capital = ₹ 3,00,000
So, for the next 6 months (October to March):
\[
\text{Interest} = \frac{3,00,000 \times 8 \times 6}{100 \times 12} = ₹ 12,000
\]
Step 3: Total interest on capital
\[
\text{Total Interest} = ₹ 16,000 + ₹ 12,000 = ₹ 28,000
\]
Note: The correct answer according to solution is ₹ 28,000, so the original marked answer (4) ₹ 32,000 may be incorrect.
Correct Answer (Updated): (1) ₹ 28,000
