Find the approx value of:- 28.01 * 7.142 + 351.99 * 24.98% = ?

Options

A. a. 320
B. b. 400
C. c. 240
D. d. 284

Answer

To find the approximate value of the expression \(28.01 \times 7.142 + 351.99 \times 24.98\%\), we can follow these steps:

### Step 1: Approximate the numbers
First, we can round the numbers to make the calculations easier:
- \(28.01\) can be approximated to \(28\).
- \(7.142\) can be approximated to \(7\).
- \(351.99\) can be approximated to \(352\).
- \(24.98\%\) can be approximated to \(25\%\), which is \(\frac{25}{100} = 0.25\).

### Step 2: Calculate the first part of the expression
Now we calculate the first part:
\[ 28 \times 7 = 196 \]

### Step 3: Calculate the second part of the expression
Next, we calculate the second part:
\[ 352 \times 0.25 = 88 \]

### Step 4: Add both parts together
Now, we can add the results from Step 2 and Step 3:
\[ 196 + 88 = 284 \]

### Final Answer
Thus, the approximate value of the expression is:
\[ \boxed{284} \]
