What approximate value should come in the place of question mark in following question.
`32.01 xx 4.99 + ? = 64.03% "of 349.97"`

Options

A. 48
B. 96
C. 72
D. 64

Answer

To solve the equation \( 32.01 \times 4.99 + ? = 64.03\% \text{ of } 349.97 \), we will follow these steps:

### Step 1: Approximate the values
First, we approximate the numbers:
- \( 32.01 \) can be approximated to \( 32 \).
- \( 4.99 \) can be approximated to \( 5 \).
- \( 64.03\% \) can be approximated to \( 64\% \).
- \( 349.97 \) can be approximated to \( 350 \).

### Step 2: Calculate \( 32 \times 5 \)
Now, we calculate:
\[ 32 \times 5 = 160 \]

### Step 3: Calculate \( 64\% \text{ of } 350 \)
Next, we calculate \( 64\% \text{ of } 350 \):
\[ 64\% \text{ of } 350 = \frac{64}{100} \times 350 = 0.64 \times 350 \]
Calculating \( 0.64 \times 350 \):
\[ 0.64 \times 350 = 224 \]

### Step 4: Set up the equation
Now we can set up the equation:
\[ 160 + ? = 224 \]

### Step 5: Solve for ?
To find the value of \( ? \), we rearrange the equation:
\[ ? = 224 - 160 \]
Calculating this gives:
\[ ? = 64 \]

### Final Answer
Thus, the approximate value that should come in place of the question mark is \( 64 \).
