What approximate value will come in place of question mark(?) in the given question ? (You are not expected to calculate the exact value)
`316div15.02xx5.99+?=11.99^2`

Options

A. 32
B. 18
C. 38
D. 8

Answer

To solve the equation \( 316 \div 15.02 \times 5.99 + ? = 11.99^2 \) and find the approximate value of \( ? \), we can follow these steps:

### Step 1: Approximate the values
We will round the numbers to make calculations easier:
- Approximate \( 316 \) to \( 315 \)
- Approximate \( 15.02 \) to \( 15 \)
- Approximate \( 5.99 \) to \( 6 \)
- Approximate \( 11.99 \) to \( 12 \)

### Step 2: Rewrite the equation
Now, we can rewrite the equation using these approximations:
\[ 315 \div 15 \times 6 + ? = 12^2 \]

### Step 3: Calculate \( 12^2 \)
Calculate the right side of the equation:
\[ 12^2 = 144 \]

### Step 4: Calculate \( 315 \div 15 \)
Now, calculate \( 315 \div 15 \):
\[ 315 \div 15 = 21 \]

### Step 5: Calculate \( 21 \times 6 \)
Next, calculate \( 21 \times 6 \):
\[ 21 \times 6 = 126 \]

### Step 6: Substitute back into the equation
Now substitute back into the equation:
\[ 126 + ? = 144 \]

### Step 7: Solve for \( ? \)
To find \( ? \), subtract \( 126 \) from \( 144 \):
\[ ? = 144 - 126 = 18 \]

Thus, the approximate value that will come in place of the question mark \( ? \) is \( 18 \).

### Final Answer:
The approximate value of \( ? \) is \( 18 \).
