Options

A. 350
B. 270
C. 360
D. 380

Answer

To find the approximate value of the question mark in the equation \( 34.99 \times 49.980 \div 175.045 = ? - 19.98\% \text{ of } 1700.03 \), we can follow these steps:

### Step 1: Approximate the values
First, we will approximate the values in the equation:
- \( 34.99 \approx 35 \)
- \( 49.980 \approx 50 \)
- \( 175.045 \approx 175 \)
- \( 19.98\% \text{ of } 1700.03 \approx 20\% \text{ of } 1700 \)

So we rewrite the equation as:
\[ 35 \times 50 \div 175 = ? - 20\% \text{ of } 1700 \]

### Step 2: Calculate \( 20\% \text{ of } 1700 \)
To find \( 20\% \text{ of } 1700 \):
\[ 20\% \text{ of } 1700 = \frac{20}{100} \times 1700 = 340 \]

### Step 3: Solve the left side of the equation
Now, we calculate \( 35 \times 50 \div 175 \):
1. Calculate \( 35 \times 50 \):
\[ 35 \times 50 = 1750 \]
2. Now divide \( 1750 \) by \( 175 \):
\[ 1750 \div 175 = 10 \]

### Step 4: Set up the equation
Now we have:
\[ 10 = ? - 340 \]

### Step 5: Solve for the question mark
To find \( ? \):
\[ ? = 10 + 340 = 350 \]

### Final Answer
Thus, the approximate value of \( ? \) is \( 350 \).
