What approximate value will come in place of the question mark(?) in the given questions? (You are not expected to calculate exact value)
`4.01xx(18.03-11.98)xx14.86=?`

Options

A. 350
B. 360
C. 370
D. 340

Answer

To find the approximate value that will come in place of the question mark (?) in the expression `4.01xx(18.03-11.98)xx14.86`, we will follow these steps:

### Step 1: Simplify the expression
The expression is structured as:
\[ 4.01 \times (18.03 - 11.98) \times 14.86 \]

### Step 2: Approximate the values
We will round each number to make calculations easier:
- Approximate \( 4.01 \) to \( 4 \)
- Approximate \( 18.03 \) to \( 18 \)
- Approximate \( 11.98 \) to \( 12 \)
- Approximate \( 14.86 \) to \( 15 \)

### Step 3: Substitute the approximated values
Now substituting the approximated values into the expression:
\[ 4 \times (18 - 12) \times 15 \]

### Step 4: Calculate the expression inside the parentheses
Calculate \( 18 - 12 \):
\[ 18 - 12 = 6 \]

### Step 5: Substitute back into the expression
Now substitute back into the expression:
\[ 4 \times 6 \times 15 \]

### Step 6: Calculate \( 4 \times 6 \)
Calculate \( 4 \times 6 \):
\[ 4 \times 6 = 24 \]

### Step 7: Calculate \( 24 \times 15 \)
Finally, calculate \( 24 \times 15 \):
\[ 24 \times 15 = 360 \]

### Final Result
Thus, the approximate value that will come in place of the question mark (?) is:
\[ \text{360} \]
