As no partnership deed exists, the Indian Partnership Act mandates interest at 6% per annum on the loan.
Loan Amount Provided = ₹ 5,00,000
Duration = 6 months (October to March)
Calculated Interest = ₹ 5,00,000 × 6% × 6/12 = ₹ 15,000
Profit post-interest deduction = ₹ 2,15,000 – ₹ 15,000 = ₹ 2,00,000
Shikha's allocated share = \( \frac{5}{20} \times 2,00,000 = ₹ 50,000 \)Final Answer: ₹ 50,000
