What approximate value will come in place of question mark (?) in the given questions? (You are not expected to calculate the exact value.)
`55.01-345.02div22.99=2xx?`

Options

A. 20
B. 25
C. 22
D. 15

Answer

To solve the equation \( 55.01 - \frac{345.02}{22.99} = 2 \times ? \), we will approximate the values involved to simplify the calculations.

### Step-by-Step Solution:

1. **Approximate the values:**
- Approximate \( 55.01 \) to \( 55 \).
- Approximate \( 345.02 \) to \( 345 \).
- Approximate \( 22.99 \) to \( 23 \).

2. **Rewrite the equation with approximations:**
\[ 55 - \frac{345}{23} = 2 \times ? \]

3. **Calculate \( \frac{345}{23} \):**
- To simplify \( \frac{345}{23} \), we can estimate it.
- \( 23 \) is close to \( 20 \), and \( 345 \) is close to \( 340 \).
- \( \frac{340}{20} = 17 \) (This is a rough estimate).

4. **Substitute the approximate division result back into the equation:**
\[ 55 - 15 \approx 2 \times ? \]

5. **Calculate \( 55 - 15 \):**
\[ 55 - 15 = 40 \]

6. **Set up the equation:**
\[ 40 = 2 \times ? \]

7. **Solve for \( ? \):**
\[ ? = \frac{40}{2} = 20 \]

### Final Answer:
The approximate value that will come in place of the question mark (?) is **20**.
