What approximate value will come in place of question mark (?) in the following questions. (You are not expected to calculate the exact value)
`58.99 + 52.11 - 47.94 + ? = 85.96 `

Options

A. 27
B. 19
C. 23
D. 15

Answer

To solve the equation \( 58.99 + 52.11 - 47.94 + ? = 85.96 \) and find the approximate value of the question mark (?), we can follow these steps:

### Step 1: Round the numbers to the nearest integers
- Round \( 58.99 \) to \( 59 \)
- Round \( 52.11 \) to \( 52 \)
- Round \( 47.94 \) to \( 48 \)
- Round \( 85.96 \) to \( 86 \)

### Step 2: Rewrite the equation with the rounded values
Now, we can rewrite the equation using the rounded values:
\[ 59 + 52 - 48 + ? = 86 \]

### Step 3: Simplify the left side of the equation
Calculate \( 59 + 52 - 48 \):
- First, add \( 59 + 52 = 111 \)
- Then, subtract \( 48 \) from \( 111 \):
\[ 111 - 48 = 63 \]

### Step 4: Substitute back into the equation
Now substitute this back into the equation:
\[ 63 + ? = 86 \]

### Step 5: Solve for the question mark (?)
To find the value of \( ? \), subtract \( 63 \) from \( 86 \):
\[ ? = 86 - 63 = 23 \]

### Conclusion
The approximate value that will come in place of the question mark (?) is \( 23 \).
