Profit for the year ended 31 March 2024 = \u20b9 2,40,000
Sales for full year = \u20b9 24,00,000
Sales till death = \u20b9 15,00,000
\[ \text{Profit till death} = \frac{15,00,000}{24,00,000} \times 2,40,000 = \u20b9 1,50,000 \]
Biswas's share = 3/10 of 1,50,000 = \u20b9 45,000
Final Answer: \u20b9 45,000
