What approximate value will come in place of questions mark (?) in the given questions? (You are not expected to calculate the exact value.)
`33.87+19.98-?-8.97=6.11`

Options

A. 39
B. 46
C. 26
D. 32

Answer

To find the approximate value that will come in place of the question mark (?) in the equation \( 33.87 + 19.98 - ? - 8.97 = 6.11 \), we can follow these steps:

### Step 1: Approximate the numbers
We will round the numbers to make calculations easier:
- \( 33.87 \) can be approximated to \( 34 \)
- \( 19.98 \) can be approximated to \( 20 \)
- \( 8.97 \) can be approximated to \( 9 \)
- \( 6.11 \) can be approximated to \( 6 \)

### Step 2: Rewrite the equation with approximations
Substituting the approximated values into the equation gives us:
\[ 34 + 20 - ? - 9 = 6 \]

### Step 3: Simplify the left-hand side
Now, we can simplify the left-hand side:
\[ 34 + 20 = 54 \]
So, the equation now looks like:
\[ 54 - ? - 9 = 6 \]

### Step 4: Combine like terms
Next, we combine \( 54 \) and \( -9 \):
\[ 54 - 9 = 45 \]
Thus, the equation simplifies to:
\[ 45 - ? = 6 \]

### Step 5: Solve for the question mark
To find the value of \( ? \), we can rearrange the equation:
\[ ? = 45 - 6 \]
Calculating this gives:
\[ ? = 39 \]

### Conclusion
Therefore, the approximate value that will come in place of the question mark (?) is \( 39 \).
