Correct Answer: Working Capital = Equity Share Capital + Reserves & Surplus - Long Term Loan - Non-Current Assets

Solution : Answer = Working Capital = Equity Share Capital + Reserves & Surplus - Long Term Loan - Non-Current Assets

Working capital is a measure of a company's short-term financial health. It indicates the ability to pay current liabilities with current assets. Equity, reserves, surplus, and long-term loans are all part of shareholders' funds (financing sources) and non-current assets (long-term investments).

Working Capital = Current Assets - Current Liabilities (This formula directly calculates the difference between what a company can access quickly and what it owes in the short term) Current Liabilities = Total Assets - Non-Current Liabilities - Shareholder’s fund (This formula subtracts long-term financing sources and investments from total assets to arrive at current liabilities).
Hence, the correct option is 3.
