Step 1: Understand the accounting treatment.
Loss on Issue of Debentures = Discount on issue of debentures + Premium on redemption of debentures.
Step 2: Calculate discount on issue.
Total Debenture Value = Rs. 1,00,000 (1,000 debentures x Rs. 100 each).
Discount = 5% of Rs. 1,00,000 = Rs. 5,000.
Step 3: Calculate premium on redemption.
Premium = 5% of Rs. 1,00,000 = Rs. 5,000.
Step 4: Total Loss on Issue.
\[\text{Loss on Issue of Debentures} = 5,000 \text{ (Discount)} + 5,000 \text{ (Premium)} = \text{Rs. } 10,000\] The problem specifies issuance at a 5% discount and redemption at a 5% premium.
- Discount = Rs. 5,000.
- Premium on redemption = Rs. 5,000.
Therefore, the total loss is Rs. 10,000.
Re-evaluation of options considering potential confusion:
If discount (Rs. 5,000) and premium (Rs. 5,000) are calculated based on the face value of Rs. 1,00,000:
- Discount: 5% of Rs. 1,00,000 = Rs. 5,000.
- Premium on redemption: 5% of Rs. 1,00,000 = Rs. 5,000.
Total Loss = Rs. 5,000 + Rs. 5,000 = Rs. 10,000.
Thus, the correct answer is Rs. 10,000.
Final Answer: \[\boxed{\text{Rs. 10,000}}\]
