1. Average Profit:
\[
\text{Average Profit} = \frac{33,000 + 22,000 + 31,000 + 34,000}{4} = ₹ 30,000.
\]
2. Goodwill (Three Years’ Purchase):
\[
\text{Goodwill} = \text{Average Profit} \times 3 = ₹ 30,000 \times 3 = ₹ 90,000.
\]
3. Normal Profit:
\[
\text{Normal Profit} = \text{Capital Employed} \times \frac{\text{Normal Rate of Return}}{100}.
\]
Capital Employed = ₹ 1,20,000 + ₹ 80,000 = ₹ 2,00,000.
\[
\text{Normal Profit} = ₹ 2,00,000 \times \frac{12}{100} = ₹ 24,000.
\]
4. Super Profit:
\[
\text{Super Profit} = \text{Average Profit} - \text{Normal Profit} = ₹ 30,000 - ₹ 24,000 = ₹ 6,000.
\]
5. Goodwill (Capitalisation of Super Profit):
\[
\text{Goodwill} = \text{Super Profit} \times \frac{100}{\text{Normal Rate of Return}} = ₹ 6,000 \times \frac{100}{12} = ₹ 50,000.
\]
Final Answers:
(i) Goodwill (Three Years’ Purchase) = ₹ 90,000.
(ii) Goodwill (Capitalisation of Super Profit) = ₹ 50,000.
