What approximate value will come in place of question mark (?) in the following questions. (You are not expected to calculate the exact value)
`779.98 div 48.014 xx 15.989 = ?`

Options

A. 280
B. 248
C. 275
D. 260

Answer

To solve the problem \( 779.98 \div 48.014 \times 15.989 = ? \) and find the approximate value, we will follow these steps:

### Step 1: Approximate Each Number
- First, we approximate each number to make calculations easier:
- \( 779.98 \) can be approximated to \( 780 \)
- \( 48.014 \) can be approximated to \( 48 \)
- \( 15.989 \) can be approximated to \( 16 \)

### Step 2: Rewrite the Expression
- Now, we can rewrite the expression using the approximated values:
\[ 780 \div 48 \times 16 \]

### Step 3: Perform the Division
- Next, we perform the division:
\[ 780 \div 48 \]
- To simplify this, we can estimate:
- \( 48 \) goes into \( 780 \) approximately \( 16.25 \) times, but for simplicity, we can round it to \( 16 \) (since \( 48 \times 16 = 768 \), which is close to \( 780 \)).

### Step 4: Multiply the Result by 16
- Now, we multiply the result of the division by \( 16 \):
\[ 16 \times 16 = 256 \]

### Step 5: Adjust for Approximation
- Since we rounded \( 780 \div 48 \) to \( 16 \), we can consider that it might be slightly higher. Thus, we can adjust our final result:
\[ 16 \times 16 = 256 \text{ (but since we approximated division, we can consider it slightly higher)} \]
- Therefore, we can estimate the final value to be around \( 260 \).

### Conclusion
- The approximate value that comes in place of the question mark is \( 260 \).

### Final Answer
\[ \text{The answer is } 260. \]
