Ridhima and Kavita's fixed capitals are ₹1,50,000 and ₹2,00,000 respectively.
The partnership deed mandates interest on capital at 8% p.a. \[ \text{Interest on capital for Ridhima} = rupee 1,50,000 \times \frac{8}{100} = rupee 12,000 \] \[ \text{Interest on capital for Kavita} = rupee 2,00,000 \times \frac{8}{100} = rupee 16,000 \]
However, the firm's net profit is ₹21,000, which is insufficient to cover the total interest on capital (₹28,000).
Consequently, the available profit will be distributed according to the ratio of interest entitlements: \[ \text{Ratio of interest entitlement} = rupee 12,000 : rupee 16,000 = 3 : 4 \] \[ \text{Adjusted interest for Ridhima} = rupee 21,000 \times \frac{3}{7} = rupee 9,000 \] \[ \text{Adjusted interest for Kavita} = rupee 21,000 \times \frac{4}{7} = rupee 12,000 \]
