`(45xx 4.5 xx 3.2)` + 343 =?

Options

A. 919
B. 991
C. 911
D. 990

Answer

To solve the question `(45 x 4.5 x 3.2) + 343 = ?`, we will follow these steps:

### Step 1: Rewrite the expression
We start with the expression:
\[ (45 \times 4.5 \times 3.2) + 343 \]

### Step 2: Simplify \(4.5\)
We can express \(4.5\) as \(\frac{45}{10}\) to make calculations easier:
\[ (45 \times \frac{45}{10} \times 3.2) + 343 \]

### Step 3: Multiply \(45\) and \(\frac{45}{10}\)
Now, calculate \(45 \times \frac{45}{10}\):
\[ = \frac{45 \times 45}{10} = \frac{2025}{10} = 202.5 \]

### Step 4: Multiply by \(3.2\)
Next, we multiply \(202.5\) by \(3.2\):
\[ 202.5 \times 3.2 \]

Calculating this gives:
\[ = 648 \]

### Step 5: Add \(343\)
Now, we add \(343\) to \(648\):
\[ 648 + 343 \]

Calculating this gives:
\[ = 991 \]

### Final Answer
Thus, the value that comes in place of the question mark is:
\[ \boxed{991} \]
