What approximate value should come in place of the question mark (?) in the following questions ? (You are not expected to calculate the exact value) ?
`(634 + 9708 - 215) div 25 = ?`

Options

A. 350
B. 425
C. 415
D. 400

Answer

To solve the expression `(634 + 9708 - 215) div 25 = ?`, we will follow these steps:

### Step 1: Simplify the expression inside the parentheses
First, we need to perform the addition and subtraction in the expression:
- Add 634 and 9708:
\[ 634 + 9708 = 10342 \]

### Step 2: Subtract 215 from the result
Now, we subtract 215 from the sum we just calculated:
- Subtract 215 from 10342:
\[ 10342 - 215 = 10127 \]

### Step 3: Divide the result by 25
Next, we divide the result by 25:
- Divide 10127 by 25:
\[ 10127 \div 25 \approx 405.08 \]

### Step 4: Approximate the result
Since we are looking for an approximate value, we round 405.08 to the nearest whole number, which is 405.

### Step 5: Choose the closest option
Now, we compare our approximate value (405) with the provided options: 350, 425, 415, and 400. The closest option to 405 is:
- **400**

Thus, the approximate value that should come in place of the question mark (?) is **400**.
