Asit’s final balance = ₹ 40,00,000
Amount paid to him = ₹ 45,00,000
Excess amount = ₹ 5,00,000 (This must be his share of goodwill)
Therefore, this ₹ 5,00,000 is Asit's share of goodwill.
His profit share = \( \frac{3}{6} = \frac{1}{2} \)
\[ \text{Goodwill of firm} = \frac{5,00,000}{1/2} = ₹ 10,00,000 \]
Final Answer: ₹ 10,00,000
