Short answer: with ₹5,00,000 of current assets against ₹2,50,000 of current liabilities the current ratio is 2.0, the quick ratio 1.6, and with ₹90,000 of net income on ₹12,00,000 of revenue the net margin is 7.5% and ROE 15%.
Liquidity, leverage and profitability
The seven ratios fall into three groups: can the business pay its short-term bills (current and quick), how is it financed (debt to equity), and does it earn (margin, ROA, ROE, coverage). Reading them together is the point — a 15% ROE funded by heavy debt looks very different from the same 15% funded by equity.
Worked example
A firm with ₹80,000 current assets and ₹1,00,000 current liabilities has a current ratio of 0.8 — it cannot cover this year's obligations from this year's liquid assets. That single number usually sends an analyst to the cash-flow statement before anything else.
