Step 1: Use the formula for calculating the percentage.
The formula for the percentage is:
\[
\text{Percentage} = \frac{\text{Amount held in cash}}{\text{Total assets}} \times 100
\]
Substitute the given values:
\[
\text{Percentage} = \frac{31,724.54}{2,377,366.30} \times 100
\]
Step 2: Calculate the percentage.
First, calculate the fraction:
\[
\frac{31,724.54}{2,377,366.30} \approx 0.0133
\]
Then multiply by 100 to convert to a percentage:
\[
0.0133 \times 100 \approx 1.3%
\]
Step 3: Conclusion.
Thus, approximately 1.3% of the total assets were held in cash on that day.
