What value will come in place of question mark(?) in the question
`(255 xx 2000) div ? xx25 = 2550`

Options

A. 500
B. 2500
C. 250
D. None of these

Answer

To solve the equation \( (255 \times 2000) \div ? \times 25 = 2550 \), we will follow these steps:

### Step 1: Write down the equation
We start with the equation:
\[ \frac{255 \times 2000}{? \times 25} = 2550 \]

### Step 2: Calculate \( 255 \times 2000 \)
Now, we calculate \( 255 \times 2000 \):
\[ 255 \times 2000 = 510000 \]
So, we can rewrite the equation as:
\[ \frac{510000}{? \times 25} = 2550 \]

### Step 3: Cross-multiply
Next, we cross-multiply to eliminate the fraction:
\[ 510000 = 2550 \times (? \times 25) \]

### Step 4: Simplify the right side
Now, we simplify the right side:
\[ 510000 = 2550? \times 25 \]
This can be rewritten as:
\[ 510000 = 63750? \]
(Here, \( 2550 \times 25 = 63750 \))

### Step 5: Solve for ?
Now, we solve for \( ? \):
\[ ? = \frac{510000}{63750} \]

### Step 6: Perform the division
Now, we perform the division:
\[ ? = 8 \]

### Step 7: Verify the calculation
To verify, we can multiply back:
\[ 63750 \times 8 = 510000 \]
This confirms our answer is correct.

### Final Answer
Thus, the value that comes in place of the question mark (?) is:
\[ \boxed{8} \]
