The current ratio is the ratio of current assets to current liabilities.
1. Payment to creditors (₹ 40,000) reduces both current assets (cash) and current liabilities (creditors) proportionally, keeping the ratio unchanged.
2. Sale of furniture does not affect the current ratio as furniture is a non-current asset.
3. Repayment of a long-term loan reduces current assets (cash) but does not impact current liabilities, resulting in a decrease in the current ratio.
4. Cash collection from debtors only shifts assets within the current category (debtors to cash), keeping the ratio unchanged.
