What should come in place of the question mark (?) in the following questions:
2234 + 84-1273 = ?+ 123. Options are (a) 922 (b) 932 (c) 159 (d) 143 .

Options

A. 922
B. 932
C. 159
D. 143

Answer

To solve the equation \( 2234 + 84 - 1273 = ? + 123 \), we will follow these steps:

### Step 1: Simplify the left side of the equation
First, we need to perform the addition and subtraction on the left side of the equation.

\[ 2234 + 84 = 2318 \]

### Step 2: Subtract 1273 from the result
Now, we will subtract 1273 from 2318.

\[ 2318 - 1273 \]

Calculating this step-by-step:
- Subtract the units: \( 8 - 3 = 5 \)
- Subtract the tens: \( 1 - 7 \) (we need to borrow, so it becomes \( 11 - 7 = 4 \))
- Subtract the hundreds: \( 2 - 2 = 0 \)
- Subtract the thousands: \( 2 - 1 = 1 \)

So, \( 2318 - 1273 = 1045 \).

### Step 3: Set up the equation
Now we have:

\[ 1045 = ? + 123 \]

### Step 4: Isolate the question mark (?)
To find the value of the question mark, we will subtract 123 from both sides of the equation:

\[ ? = 1045 - 123 \]

Calculating this:

\[ 1045 - 123 \]

Again, step-by-step:
- Subtract the units: \( 5 - 3 = 2 \)
- Subtract the tens: \( 4 - 2 = 2 \)
- Subtract the hundreds: \( 10 - 1 = 9 \)

Thus, \( 1045 - 123 = 922 \).

### Final Answer
The value that should come in place of the question mark is:

\[ ? = 922 \]

### Options
Looking at the options provided:
(a) 922 (b) 932 (c) 159 (d) 143

The correct answer is **(a) 922**.
