What will come in place of question mark(?) in the following questions?
`(3.5xx1.35xx4.5)/(0.5)=?`

Options

A. 35.135
B. 20.525
C. 40.415
D. None of these

Answer

To solve the expression \((3.5 \times 1.35 \times 4.5) / 0.5\), we will follow these steps:

### Step 1: Multiply the numbers in the numerator
First, we will calculate the product of \(3.5\), \(1.35\), and \(4.5\).

\[ 3.5 \times 1.35 = 4.725 \]

Next, we will multiply this result by \(4.5\):

\[ 4.725 \times 4.5 = 21.2625 \]

### Step 2: Divide by \(0.5\)
Now, we will divide the result from Step 1 by \(0.5\):

\[ 21.2625 / 0.5 = 21.2625 \times 2 = 42.525 \]

### Final Answer
Thus, the value that comes in place of the question mark (?) is:

\[ \boxed{42.525} \]
