The current ratio, defined as current assets divided by current liabilities, is affected by the following transactions:
1. Payment to creditors (₹ 40,000) impacts both current assets (cash) and current liabilities (creditors) equally, thus maintaining the ratio.
2. The sale of furniture, a non-current asset, has no effect on the current ratio.
3. Repaying a long-term loan decreases current assets (cash) but does not alter current liabilities, leading to a reduced current ratio.
4. Collecting cash from debtors merely reallocates assets within the current category (from debtors to cash), leaving the current ratio constant.
