Final answer:
The acid-test ratio of the company is 0.93.
Step-by-step explanation:
The acid-test ratio of a company is calculated by adding up its cash, short-term investments, and net current receivables, and then dividing that sum by the total current liabilities.
The acid-test ratio is a measure of a company's ability to pay off its current liabilities using only its most liquid assets. In this case, the company has $50,000 in cash, $85,000 in short-term investments, and $120,000 in net current receivables, which adds up to $255,000. Dividing this by the total current liabilities of $275,000 will give us the acid-test ratio:
Acid-test ratio = ($50,000 + $85,000 + $120,000) / $275,000 = 0.93
Therefore, the acid-test ratio of the company is 0.93, which is option a).
