Step 1: Calculate total capital of old partners.
Hemant's capital = Rs 80,000.
Naman's capital = Rs 50,000.
Total old capital = Rs 1,30,000 (80,000 + 50,000).
Step 2: Determine firm's total capital based on Samrat's share.
Samrat's capital for 1/5 share = Rs 60,000.
Firm's total capital = Rs 3,00,000 (60,000 × 5).
Step 3: Calculate the firm's goodwill.
Expected total capital = Rs 3,00,000.
Actual combined capital (Hemant + Naman + Samrat) = Rs 1,90,000 (1,30,000 + 60,000).
Goodwill = Rs 1,10,000 (3,00,000 – 1,90,000).
Step 4: Verify calculations.
Goodwill is the excess of total capital over actual capital.
Recalculation: Total firm capital = Rs 3,00,000.
Actual capital = Hemant (80,000) + Naman (50,000) + Samrat (60,000) = Rs 1,90,000.
Goodwill = Rs 1,10,000 (3,00,000 – 1,90,000). Correct goodwill value = Rs 1,10,000.
Final Answer: \[\boxed{\text{Rs. 1,10,000}}\]
