What will come in place of the question mark (?) in the following questions ?
`sqrt((625))xx12-864-:24=?+71`

Options

A. 193
B. 183
C. 181
D. 190

Answer

To solve the equation \( \sqrt{625} \times 12 - \frac{864}{24} = ? + 71 \), we will follow the order of operations (BODMAS/BIDMAS).

### Step-by-Step Solution:

1. **Calculate the square root of 625**:
\[ \sqrt{625} = 25 \]

**Hint**: Remember that the square root of a number is a value that, when multiplied by itself, gives the original number.

2. **Multiply the result by 12**:
\[ 25 \times 12 = 300 \]

**Hint**: Multiplication is straightforward; just multiply the two numbers together.

3. **Divide 864 by 24**:
\[ \frac{864}{24} = 36 \]

**Hint**: Division can be simplified by canceling out common factors if possible.

4. **Subtract the result of the division from the multiplication**:
\[ 300 - 36 = 264 \]

**Hint**: When subtracting, ensure you align the numbers correctly to avoid mistakes.

5. **Set up the equation**:
\[ 264 = ? + 71 \]

**Hint**: This equation shows that you need to isolate the question mark.

6. **Isolate the question mark**:
\[ ? = 264 - 71 \]
\[ ? = 193 \]

**Hint**: To isolate a variable, you can perform the opposite operation on both sides of the equation.

### Final Answer:
The value that comes in place of the question mark (?) is **193**.
