What will come in the place of question mark (?) in following questions?
`12839+62591-34812`= ?

Options

A. 40618
B. 41806
C. 62148
D. 48610

Answer

To solve the expression \( 12839 + 62591 - 34812 \), we will follow these steps:

### Step 1: Perform the Addition
First, we need to add \( 12839 \) and \( 62591 \).

\[ 12839 + 62591 \]

Aligning the numbers for addition:

```
12839
+ 62591
--------
```

Now, we add column by column starting from the right:

- **Units place**: \( 9 + 1 = 10 \) (write down 0 and carry over 1)
- **Tens place**: \( 3 + 9 + 1 = 13 \) (write down 3 and carry over 1)
- **Hundreds place**: \( 8 + 5 + 1 = 14 \) (write down 4 and carry over 1)
- **Thousands place**: \( 2 + 2 + 1 = 5 \) (write down 5)
- **Ten-thousands place**: \( 1 + 6 = 7 \) (write down 7)

So, the result of the addition is:

\[ 12839 + 62591 = 75430 \]

### Step 2: Perform the Subtraction
Now, we need to subtract \( 34812 \) from \( 75430 \).

\[ 75430 - 34812 \]

Aligning the numbers for subtraction:

```
75430
- 34812
--------
```

Now, we subtract column by column starting from the right:

- **Units place**: \( 0 - 2 \) (we need to borrow, so it becomes \( 10 - 2 = 8 \))
- **Tens place**: \( 3 - 1 = 2 \)
- **Hundreds place**: \( 4 - 8 \) (we need to borrow, so it becomes \( 14 - 8 = 6 \))
- **Thousands place**: \( 5 - 4 = 1 \)
- **Ten-thousands place**: \( 7 - 3 = 4 \)

So, the result of the subtraction is:

\[ 75430 - 34812 = 40618 \]

### Final Answer
Thus, the value that comes in place of the question mark (?) is:

\[ \boxed{40618} \]
