20.4×5-32.40×5= ?
What will come in place of the question mark (?) in the following questions?

The correct option is -60.

To find the value of the question mark (?), we need to evaluate the following arithmetic expression step-by-step:

$(20.4\times 5)-(32.40\times 5)$

Step 1: Calculate the product of the first term, $20.4\times 5$.
$20.4\times 5=102$

Step 2: Calculate the product of the second term, $32.40\times 5$.
$32.40\times 5=162$

Step 3: Subtract the second result from the first result.
$102-162=-60$

Alternatively, we can factor out the common multiplier, 5:
$(20.4-32.40)\times 5$
$=-12\times 5=-60$

Therefore, the value that comes in place of the question mark (?) is -60.
