Number of debentures = 2,00,000
Face value per debenture = \u20b9 100
Rate of interest = 8% annually
\[ \text{Total Face Value} = 2,00,000 \times 100 = \u20b9 2,00,00,000 \]
\[ \text{Annual Interest} = 8% \times 2,00,00,000 = \u20b9 16,00,000 \]
Interest is payable half-yearly, so two installments:
\[ \frac{16,00,000}{2} = \u20b9 8,00,000 \text{ each half year} \]
For the year ended 31st March, 2024, total interest paid = \u20b9 16,00,000
But interest is paid on nominal value even if issued at discount.
However, since discount doesn't affect interest calculation, and 2 payments made (Sept and March), total = \u20b9 16,00,000
Interest written off = \u20b9 16,00,000 - \u20b9 1,60,000 (10% discount on issue = capital loss amortized over 10 years)
= \u20b9 14,40,000
Final Answer: \u20b9 14,40,000
