D. The quick ratio is calculated as quick assets (current assets excluding inventory and prepaid expenses) divided by current liabilities. Quick assets include accounts receivable ($200,000) and cash ($100,000). Current liabilities include accounts payable ($80,000), interest payable ($10,000) and notes payable ($50,000). Note that even though the notes payable are due after the operating cycle is over, the distinction for a current asset or liability is that it will be converted or settled within 12 months or the operating cycle, whichever is longer. The total current assets are $300,000 and current liabilities are $140,000. This gives us a quick ratio of 2.14.
