Final answer:
The percentage of current assets as of December 31, 20x9 is approximately 30.23%.
Step-by-step explanation:
To calculate the percentage of current assets as of December 31, 20x9, we need to determine the total current assets and then find the percentage it represents out of the total assets. In this case, the current assets consist of reserves, bonds, and loans. Adding their values, we have 30 + 50 + 50 = 130.
Now, to find the percentage, we divide the current assets by the total assets (current assets + liabilities). The total assets are 130 + 300 = 430. Divide 130 by 430 and multiply by 100 to get the percentage: (130/430) * 100 = 30.23%. Therefore, the percentage of current assets as of December 31, 20x9 is approximately 30.23%.
