What should come in place of question mark (?) in following questions ?
? + 432 - 205 = 550

Options

A. 384
B. 244
C. 224
D. 323

Answer

To solve the equation \( ? + 432 - 205 = 550 \), we will follow these steps:

### Step 1: Rewrite the equation
We start with the equation:
\[ ? + 432 - 205 = 550 \]

### Step 2: Simplify the left side
First, we can simplify the left side by combining the constants \(432\) and \(-205\):
\[ ? + (432 - 205) = 550 \]
Calculating \(432 - 205\):
\[ 432 - 205 = 227 \]
So, the equation now looks like:
\[ ? + 227 = 550 \]

### Step 3: Isolate the question mark
Next, we need to isolate the question mark by subtracting \(227\) from both sides of the equation:
\[ ? = 550 - 227 \]

### Step 4: Perform the subtraction
Now, we calculate \(550 - 227\):
\[ 550 - 227 = 323 \]

### Step 5: Conclusion
Thus, the value that should come in place of the question mark is:
\[ ? = 323 \]

### Final Answer
The answer is \(323\).
