What will come in place of question mark (?) in the following questions
`28.5 xx 34 + 2320 div 8 = (36)^(2) - ?`

Options

A. 51
B. 47
C. 43
D. 37

Answer

To solve the equation \( 28.5 \times 34 + \frac{2320}{8} = 36^2 - ? \), we will follow the order of operations (BODMAS/BIDMAS).

### Step-by-Step Solution:

1. **Calculate \( 28.5 \times 34 \)**:
\[ 28.5 \times 34 = 969 \]

2. **Calculate \( \frac{2320}{8} \)**:
\[ \frac{2320}{8} = 290 \]

3. **Add the results from steps 1 and 2**:
\[ 969 + 290 = 1259 \]

4. **Calculate \( 36^2 \)**:
\[ 36^2 = 1296 \]

5. **Set up the equation**:
\[ 1259 = 1296 - ? \]

6. **Rearrange to find \( ? \)**:
\[ ? = 1296 - 1259 \]

7. **Calculate \( 1296 - 1259 \)**:
\[ ? = 37 \]

Thus, the value that comes in place of the question mark (?) is **37**.
