What approximate value will come in place of question mark in the given questions?
`(3.99xx7.9xx31.99)/127.99+29.99=?`

Options

A. 33
B. 48
C. 28
D. 38

Answer

To solve the expression \((3.99 \times 7.9 \times 31.99) / 127.99 + 29.99\) and find the approximate value that comes in place of the question mark, we can follow these steps:

### Step 1: Approximate the values
- \(3.99\) can be approximated to \(4\).
- \(7.9\) can be approximated to \(8\).
- \(31.99\) can be approximated to \(32\).
- \(127.99\) can be approximated to \(128\).
- \(29.99\) can be approximated to \(30\).

### Step 2: Substitute the approximated values into the expression
Now we can rewrite the expression using the approximated values:
\[ (4 \times 8 \times 32) / 128 + 30 \]

### Step 3: Calculate the multiplication
First, calculate \(4 \times 8\):
\[ 4 \times 8 = 32 \]
Next, multiply the result by \(32\):
\[ 32 \times 32 = 1024 \]

### Step 4: Perform the division
Now, divide \(1024\) by \(128\):
\[ 1024 / 128 = 8 \]

### Step 5: Add the result to \(30\)
Now add \(30\) to the result from the division:
\[ 8 + 30 = 38 \]

### Conclusion
The approximate value that comes in place of the question mark is:
\[ \text{Question mark} = 38 \]
