1. Proceeds from Sale of Machinery:
\[
\text{Proceeds from Sale} = ₹ 62,000
\]
2. Purchase of New Machinery:
\[
\text{Increase in Plant and Machinery} = ₹ 4,10,000 - ₹ 3,00,000 = ₹ 1,10,000
\]
3. Investment in Goodwill:
\[
\text{Increase in Goodwill} = ₹ 1,80,000 - ₹ 80,000 = ₹ 1,00,000
\]
4. Net Cash Flows from Investing Activities:
\[
\text{Cash Flows from Investing Activities} = \text{Proceeds from Sale of Machinery} - \text{Purchase of Machinery} - \text{Investment in Goodwill}
\]
\[
= ₹ 62,000 - ₹ 1,10,000 - ₹ 1,00,000 = -₹ 1,48,000
\]
Final Answer: Net Cash Flows from Investing Activities = \(-₹ 1,48,000\).
