What should come in place of the question mark (?) in the following questions:
56.703-63.179+49.361=?

Options

A. 41.785
B. 41.885
C. 42.895
D. 42.885

Answer

To solve the expression \( 56.703 - 63.179 + 49.361 \), we will follow these steps:

### Step 1: Add the first two numbers
We start with the addition of \( 56.703 \) and \( 49.361 \).

\[ 56.703 + 49.361 \]

Aligning the numbers for addition:

```
56.703
+ 49.361
---------
```

Now, we add the numbers column by column from right to left:

- Thousandths place: \( 3 + 1 = 4 \)
- Hundredths place: \( 0 + 6 = 6 \)
- Tenths place: \( 7 + 3 = 10 \) (write down 0 and carry over 1)
- Units place: \( 6 + 9 + 1 (carry) = 16 \) (write down 6 and carry over 1)
- Tens place: \( 5 + 4 + 1 (carry) = 10 \)

So, the sum is:

\[ 106.064 \]

### Step 2: Subtract the third number
Now, we subtract \( 63.179 \) from \( 106.064 \).

\[ 106.064 - 63.179 \]

Aligning the numbers for subtraction:

```
106.064
- 63.179
----------
```

Now, we subtract the numbers column by column from right to left:

- Thousandths place: \( 4 - 9 \) (we need to borrow, so it becomes \( 14 - 9 = 5 \))
- Hundredths place: \( 6 - 7 \) (we need to borrow, so it becomes \( 16 - 7 = 9 \))
- Tenths place: \( 0 - 1 \) (we need to borrow, so it becomes \( 10 - 1 = 9 \))
- Units place: \( 5 - 3 = 2 \)
- Tens place: \( 10 - 6 = 4 \)

So, the result of the subtraction is:

\[ 42.885 \]

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

\[ \boxed{42.885} \]
