What will come in place of the question mark (?) in the following questions ?
`24xx114-:19-?=312-:13`

Options

A. 122
B. 124
C. 112
D. 120

Answer

To solve the equation \( 24 \times 114 \div 19 - ? = 312 \div 13 \), we will follow the order of operations (BODMAS/BIDMAS).

### Step-by-Step Solution:

1. **Calculate \( 312 \div 13 \)**:
\[ 312 \div 13 = 24 \]
(Since \( 13 \times 24 = 312 \))

2. **Rewrite the equation**:
Now we can rewrite the equation as:
\[ 24 \times 114 \div 19 - ? = 24 \]

3. **Calculate \( 24 \times 114 \div 19 \)**:
First, we perform the division:
\[ 114 \div 19 = 6 \]
(Since \( 19 \times 6 = 114 \))

Now substitute this back into the equation:
\[ 24 \times 6 - ? = 24 \]

4. **Calculate \( 24 \times 6 \)**:
\[ 24 \times 6 = 144 \]

5. **Substitute back into the equation**:
Now we have:
\[ 144 - ? = 24 \]

6. **Isolate the question mark**:
To find \( ? \), we rearrange the equation:
\[ ? = 144 - 24 \]

7. **Calculate the value of \( ? \)**:
\[ ? = 120 \]

### Final Answer:
The value that comes in place of the question mark (?) is **120**.
