What approximate value will come in place of the question mark (?) in the following questions ? (Note: You are not expected to calculate the exact value)
`6394+25 xx 12 xx 2.99`= ?

Options

A. 7291
B. 7200
C. 9300
D. 9400

Answer

To solve the expression \( 6394 + 25 \times 12 \times 2.99 \) and find the approximate value, we can follow these steps:

### Step 1: Simplify the expression
First, we can approximate \( 2.99 \) to \( 3 \). This makes calculations easier.

### Step 2: Calculate \( 25 \times 12 \)
Next, we calculate \( 25 \times 12 \):
\[ 25 \times 12 = 300 \]

### Step 3: Multiply by the approximate value of \( 2.99 \)
Now, we multiply the result by the approximate value of \( 2.99 \):
\[ 300 \times 3 = 900 \]

### Step 4: Add to \( 6394 \)
Now we add this result to \( 6394 \):
\[ 6394 + 900 = 7294 \]

### Step 5: Adjust for the approximation
Since we approximated \( 2.99 \) as \( 3 \), we need to adjust for this approximation. The difference is:
\[ 300 \times (3 - 2.99) = 300 \times 0.01 = 3 \]
So we subtract \( 3 \) from \( 7294 \):
\[ 7294 - 3 = 7291 \]

### Final Answer
Thus, the approximate value of the expression is:
\[ \boxed{7291} \]
