Step 1: Calculation of Premiums and Loss on Issue
1. Issue Price per Debenture:
\[
\text{Nominal Value} = \rupee100, \quad \text{Premium on Issue} = \rupee6.
\]
\[
\text{Total Issue Price per Debenture} = \rupee100 + \rupee6 = \rupee106.
\]
2. Redemption Price per Debenture:
\[
\text{Nominal Value} = \rupee100, \quad \text{Premium on Redemption} = \rupee4.
\]
\[
\text{Total Redemption Price per Debenture} = \rupee100 + \rupee4 = \rupee104.
\]
3. Loss on Issue of Debentures:
\[
\text{Loss on Redemption per Debenture} = \rupee104 - \rupee106 = \rupee2.
\]
\[
\text{Total Loss on Issue of Debentures} = \rupee2 \times 10,000 = \rupee20,000.
