What approximate value will come in place of question mark in the given questions?
`16.99+71.01=?xx2.01xx3.99`

Options

A. 6
B. 31
C. 25
D. 11

Answer

To solve the equation \( 16.99 + 71.01 = ? \times 2.01 \times 3.99 \), we can follow these steps:

### Step 1: Approximate the numbers
We can round the numbers to make the calculations easier:
- \( 16.99 \) is approximately \( 17 \)
- \( 71.01 \) is approximately \( 71 \)

### Step 2: Add the approximated values
Now, we add the approximated values:
\[ 17 + 71 = 88 \]

### Step 3: Approximate the multipliers
Next, we approximate the multipliers:
- \( 2.01 \) is approximately \( 2 \)
- \( 3.99 \) is approximately \( 4 \)

### Step 4: Multiply the approximated multipliers
Now, we multiply the approximated multipliers:
\[ 2 \times 4 = 8 \]

### Step 5: Set up the equation
Now we can set up the equation:
\[ 88 = ? \times 8 \]

### Step 6: Solve for the question mark
To find the value of \( ? \), we divide both sides by \( 8 \):
\[ ? = \frac{88}{8} = 11 \]

### Conclusion
Thus, the approximate value that will come in place of the question mark is \( 11 \).
