What approximate value will come in place of question mark(?)in given questions
`sqrt?xx359.88div12.01=289-109.992`

Options

A. 4
B. 16
C. 64
D. 36

Answer

To solve the equation given in the question, we will follow these steps:

1. **Set up the equation**:
We start with the equation:
\[ \sqrt{?} \times 359.88 \div 12.01 = 289 - 109.992 \]

2. **Simplify the right side**:
Calculate \( 289 - 109.992 \):
\[ 289 - 109.992 \approx 179.008 \quad (\text{approximately } 179) \]

3. **Approximate the values**:
We can round \( 359.88 \) to \( 360 \) and \( 12.01 \) to \( 12 \):
\[ \sqrt{?} \times 360 \div 12 = 179 \]

4. **Simplify the left side**:
Dividing \( 360 \) by \( 12 \):
\[ 360 \div 12 = 30 \]
So, the equation now becomes:
\[ \sqrt{?} \times 30 = 179 \]

5. **Isolate the square root**:
Divide both sides by \( 30 \):
\[ \sqrt{?} = \frac{179}{30} \]

6. **Calculate the right side**:
Performing the division:
\[ \frac{179}{30} \approx 5.9667 \quad (\text{approximately } 6) \]

7. **Square both sides**:
To find the value of \( ? \), square both sides:
\[ ? = 6^2 = 36 \]

Thus, the approximate value that will come in place of the question mark (?) is **36**.
