D. 5500

Answer

To solve the question \( 161\% \) of \( 3578 + 139.95 + \frac{5}{8} \) of \( 161.56 \), we can break it down into three parts and approximate each part.

### Step 1: Calculate \( 161\% \) of \( 3578 \)

1. Convert \( 161\% \) to a decimal:
\[ 161\% = \frac{161}{100} = 1.61 \]
2. Multiply by \( 3578 \):
\[ 1.61 \times 3578 \approx 1.6 \times 3600 = 5760 \]

### Step 2: Approximate \( 139.95 \)

1. Round \( 139.95 \) to the nearest whole number:
\[ 139.95 \approx 140 \]

### Step 3: Calculate \( \frac{5}{8} \) of \( 161.56 \)

1. First, approximate \( 161.56 \) to \( 162 \) (since \( 161.56 \) is closer to \( 162 \)).
2. Calculate \( \frac{5}{8} \) of \( 162 \):
\[ \frac{5}{8} \times 162 = \frac{5 \times 162}{8} = \frac{810}{8} = 101.25 \]

### Step 4: Add all the approximated values together

1. Combine the results from Steps 1, 2, and 3:
\[ 5760 + 140 + 101.25 \approx 5760 + 140 + 101 = 6001.25 \]

### Final Answer

Since we are looking for an approximate value, we can round \( 6001.25 \) to \( 6000 \).

Thus, the final answer is:
\[ \text{Answer} \approx 6000 \]
