Profit on Revaluation = ₹60,000 − ₹8,000 = ₹52,000
To be distributed among partners in old ratio (Aryan : Adya = 3 : 1):
\[ \text{Aryan’s Share} = ₹52,000 × \frac{3}{4} = ₹39,000 \\ \text{Adya’s Share} = ₹52,000 × \frac{1}{4} = ₹13,000 \]
\[ \text{Goodwill of firm} = ₹2,00,000 \\ \text{Dev’s Share} = \frac{1}{5} × ₹2,00,000 = ₹40,000 \]
To be distributed in sacrificing ratio (Aryan : Adya = 3 : 1):
\[ \text{Aryan} = ₹40,000 × \frac{3}{4} = ₹30,000 \\ \text{Adya} = ₹40,000 × \frac{1}{4} = ₹10,000 \]
\[ \text{Aryan’s Capital (after revaluation and goodwill)} = ₹3,20,000 + ₹39,000 + ₹30,000 = ₹3,89,000 \\ \text{Adya’s Capital (after revaluation and goodwill)} = ₹2,40,000 + ₹13,000 + ₹10,000 = ₹2,63,000 \]
\[ \text{Total capital of firm} = ₹3,89,000 + ₹2,63,000 = ₹6,52,000 \\ \text{Dev’s 1/5 share} = \frac{1}{5} × ₹6,52,000 = ₹1,63,000 \]
