Step 1: Understand the components.
Veebee Ltd. issued 20,000 debentures, each with a face value of ₹ 100. Interest is calculated on the face value, regardless of whether the debentures were issued at a discount or redeemed at a premium.
Step 2: Calculate face value and interest.
\[\text{Face value of debentures} = 20,000 \times 100 = ₹ 20,00,000\]\[\text{Interest @ 13%} = 13\% \times 20,00,000 = ₹ 2,60,000\]As the debentures were issued on April 1st, 2023, the full year's interest is applicable.
Final Answer:
\( \boxed{₹ 2,60,000} \)
