What approximte value will come in place of question mark (?) in the given question?
`?xx3xx17.99+5.002xx23.99=606.12`

Options

A. 2
B. (-3)
C. 9
D. (-2)

Answer

To solve the equation \( ? \times 3 \times 17.99 + 5.002 \times 23.99 = 606.12 \), we will first approximate the values involved and then solve for the unknown.

### Step 1: Approximate the values
We can round \( 17.99 \) to \( 18 \) and \( 23.99 \) to \( 24 \) for easier calculations.

### Step 2: Rewrite the equation
The equation becomes:
\[ ? \times 3 \times 18 + 5.002 \times 24 = 606.12 \]

### Step 3: Calculate \( 5.002 \times 24 \)
Now, we can approximate \( 5.002 \) to \( 5 \):
\[ 5 \times 24 = 120 \]

### Step 4: Substitute back into the equation
Now substitute back into the equation:
\[ ? \times 54 + 120 = 606.12 \]

### Step 5: Isolate the term with the unknown
Subtract \( 120 \) from both sides:
\[ ? \times 54 = 606.12 - 120 \]
\[ ? \times 54 = 486.12 \]

### Step 6: Solve for the unknown
Now, divide both sides by \( 54 \):
\[ ? = \frac{486.12}{54} \]

### Step 7: Calculate the division
Calculating the division gives:
\[ ? \approx 9 \]

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