What approximate value will come in place of question mark(?) in the questions given below?
`69.899 xx 4.002 xx 15.989` =?

Options

A. 4200
B. 4400
C. 4800
D. 4500

Answer

To solve the problem of finding the approximate value of \( 69.899 \times 4.002 \times 15.989 \), we can follow these steps:

### Step 1: Round off the numbers
- Round \( 69.899 \) to the nearest whole number:
\[ 69.899 \approx 70 \]
- Round \( 4.002 \) to the nearest whole number:
\[ 4.002 \approx 4 \]
- Round \( 15.989 \) to the nearest whole number:
\[ 15.989 \approx 16 \]

### Step 2: Multiply the rounded numbers
Now we can multiply the rounded values:
\[ 70 \times 4 \times 16 \]

### Step 3: Calculate the multiplication
First, multiply \( 70 \) and \( 4 \):
\[ 70 \times 4 = 280 \]
Next, multiply the result by \( 16 \):
\[ 280 \times 16 \]

To calculate \( 280 \times 16 \):
\[ 280 \times 16 = 4480 \]

### Step 4: Conclusion
The approximate value of \( 69.899 \times 4.002 \times 15.989 \) is:
\[ 4480 \]

### Final Answer
Thus, the value that will come in place of the question mark (?) is approximately \( 4480 \).
