What approximate value will come in place of the question mark (?) in the following question?
`244.03 - 654.02 + ? -: 2.01 = 835.01`

Options

A. 2520
B. 2460
C. 2370
D. 2490

Answer

To solve the equation \( 244.03 - 654.02 + ? \div 2.01 = 835.01 \), we will first approximate the numbers for easier calculations.

### Step 1: Approximate the numbers
- Approximate \( 244.03 \) to \( 244 \)
- Approximate \( 654.02 \) to \( 654 \)
- Approximate \( 2.01 \) to \( 2 \)
- Approximate \( 835.01 \) to \( 835 \)

So, the equation becomes:
\[ 244 - 654 + ? \div 2 = 835 \]

### Step 2: Simplify the equation
Now, simplify \( 244 - 654 \):
\[ 244 - 654 = -410 \]

Now the equation is:
\[ -410 + ? \div 2 = 835 \]

### Step 3: Isolate the variable
To isolate the variable, we can add \( 410 \) to both sides:
\[ ? \div 2 = 835 + 410 \]
\[ ? \div 2 = 1245 \]

### Step 4: Solve for the variable
Now, multiply both sides by \( 2 \) to solve for \( ? \):
\[ ? = 1245 \times 2 \]
\[ ? = 2490 \]

Thus, the approximate value that will come in place of the question mark (?) is **2490**.
