D. 16

Answer

To solve the equation \( (33.33 \times 80.989 \div 99.99) + 3.024 - ? = 4.012 \) and find the approximate value of the question mark (?), we can follow these steps:

### Step 1: Rewrite the equation
We start with the equation:
\[ (33.33 \times 80.989 \div 99.99) + 3.024 - ? = 4.012 \]
We can denote the unknown value as \( x \):
\[ (33.33 \times 80.989 \div 99.99) + 3.024 - x = 4.012 \]

### Step 2: Isolate \( x \)
To isolate \( x \), we can rearrange the equation:
\[ (33.33 \times 80.989 \div 99.99) + 3.024 = 4.012 + x \]
Thus,
\[ x = (33.33 \times 80.989 \div 99.99) + 3.024 - 4.012 \]

### Step 3: Approximate the values
Next, we will approximate the values:
- \( 33.33 \) is approximately \( 33 \).
- \( 80.989 \) is approximately \( 81 \).
- \( 99.99 \) is approximately \( 100 \).
- \( 3.024 \) is approximately \( 3 \).
- \( 4.012 \) is approximately \( 4 \).

### Step 4: Substitute the approximated values
Substituting the approximated values into the equation gives us:
\[ x = \left(33 \times 81 \div 100\right) + 3 - 4 \]

### Step 5: Perform the multiplication and division
Calculate \( 33 \times 81 \):
\[ 33 \times 81 = 2673 \]
Now divide by \( 100 \):
\[ 2673 \div 100 = 26.73 \]

### Step 6: Substitute back into the equation
Now substitute back into the equation for \( x \):
\[ x = 26.73 + 3 - 4 \]
This simplifies to:
\[ x = 26.73 + 3 - 4 = 26.73 + (-1) = 25.73 \]

### Step 7: Round to the nearest integer
Since we are looking for an approximate value, we round \( 25.73 \) to the nearest integer:
\[ x \approx 26 \]

### Final Answer
Thus, the approximate value that will come in place of the question mark (?) is:
\[ \boxed{26} \]
