What should come in place of question mark (?) in the following questions?
`383div25xx2.5+12=?`

Options

A. `68.30`
B. 222.14
C. `50.30`
D. 124.24

Answer

To solve the equation \( 383 \div 25 \times 2.5 + 12 = ? \), we will follow the order of operations, often remembered by the acronym BODMAS (Brackets, Orders, Division and Multiplication, Addition and Subtraction).

### Step-by-Step Solution:

1. **Perform the Division**:
\[ 383 \div 25 \]
When we divide 383 by 25, we get:
\[ 383 \div 25 = 15.32 \]

2. **Multiply the Result by 2.5**:
\[ 15.32 \times 2.5 \]
Now, we multiply the result from the first step by 2.5:
\[ 15.32 \times 2.5 = 38.3 \]

3. **Add 12 to the Result**:
\[ 38.3 + 12 \]
Finally, we add 12 to the result from the second step:
\[ 38.3 + 12 = 50.3 \]

4. **Final Answer**:
Therefore, the value that should come in place of the question mark is:
\[ ? = 50.3 \]
