What approximate value will come in place of the question mark (?) in the following equations ?
`127.001 xx 7.998 + 6.05 xx 4.001 = ?`

Options

A. 1440
B. 1400
C. 1000
D. 1040

Answer

To solve the equation \(127.001 \times 7.998 + 6.05 \times 4.001 = ?\) and find the approximate value, we can follow these steps:

### Step 1: Round the numbers for approximation
We will round the numbers to make the calculations simpler:
- \(127.001 \approx 127\)
- \(7.998 \approx 8\)
- \(6.05 \approx 6\)
- \(4.001 \approx 4\)

### Step 2: Substitute the rounded values into the equation
Now we substitute the rounded values into the equation:
\[ 127 \times 8 + 6 \times 4 \]

### Step 3: Calculate the products
Now we will calculate each multiplication:
1. \(127 \times 8\)
\[ 127 \times 8 = 1016 \]
2. \(6 \times 4\)
\[ 6 \times 4 = 24 \]

### Step 4: Add the results
Now we will add the results of the multiplications:
\[ 1016 + 24 = 1040 \]

### Final Answer
Thus, the approximate value that will come in place of the question mark (?) is:
\[ \boxed{1040} \]
