What approximate value will come in place of question mark (?) in the following questions. (You are not expected to calculate the exact value)
`(11.01 + 12.97) xx (1)/(7.99) + 5.956 = 18 - ?`

Options

A. 15
B. 13
C. 5
D. 9

Answer

To solve the equation \( (11.01 + 12.97) \times \frac{1}{7.99} + 5.956 = 18 - ? \), we will approximate the values and find the value of the question mark step by step.

### Step 1: Approximate the values
- Round \( 11.01 \) to \( 11 \)
- Round \( 12.97 \) to \( 13 \)
- Round \( 7.99 \) to \( 8 \)
- Round \( 5.956 \) to \( 6 \)

### Step 2: Rewrite the equation with approximated values
Now, substituting the approximated values into the equation:
\[ (11 + 13) \times \frac{1}{8} + 6 = 18 - ? \]

### Step 3: Simplify the left side
Calculate \( 11 + 13 \):
\[ 24 \times \frac{1}{8} + 6 = 18 - ? \]

### Step 4: Perform the multiplication
Now, calculate \( 24 \times \frac{1}{8} \):
\[ 3 + 6 = 18 - ? \]

### Step 5: Combine the terms on the left side
Now, add \( 3 + 6 \):
\[ 9 = 18 - ? \]

### Step 6: Solve for the question mark
Rearranging gives:
\[ ? = 18 - 9 \]
\[ ? = 9 \]

### Final Answer
The approximate value that will come in place of the question mark is \( 9 \).
