What approximate value will come in place of question mark (?) in the question given below?
नीचे दिए गए प्रश्न मे प्रश्नवाचक चिन्ह (?) के स्थान पर लगभग कितना मान आएगा?
`404.24-4.04+123.78–?=99.84`

Options

A. 424
B. 130
C. 120
D. 115

Answer

To solve the equation \( 404.24 - 4.04 + 123.78 - ? = 99.84 \), we will follow these steps:

### Step 1: Approximate the values
We will round the numbers to make calculations easier:
- \( 404.24 \approx 404 \)
- \( 4.04 \approx 4 \)
- \( 123.78 \approx 124 \)
- \( 99.84 \approx 100 \)

So, the equation simplifies to:
\[ 404 - 4 + 124 - ? = 100 \]

### Step 2: Simplify the left side
Now, we will perform the arithmetic on the left side:
1. Calculate \( 404 - 4 \):
\[ 404 - 4 = 400 \]

2. Add \( 124 \):
\[ 400 + 124 = 524 \]

So, the equation now looks like:
\[ 524 - ? = 100 \]

### Step 3: Isolate the question mark
To find the value of \( ? \), we can rearrange the equation:
\[ ? = 524 - 100 \]

### Step 4: Calculate the value
Now, we perform the subtraction:
\[ 524 - 100 = 424 \]

Thus, the approximate value that will come in place of the question mark (?) is:
\[ ? \approx 424 \]

### Final Answer
The approximate value for the question mark is \( 424 \).
