Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Let the  number be $x$

We know, $32570>23570$

$\therefore$  $(x-32570)<(x-23570)$
$\Rightarrow$  The difference between the numbers $=32570-23570$
                                                                      $=9000$

$\therefore$  We can say that, instead of subtracting $32570$ from number, if $23570$ is subtracted, then the answer can be increase by $9000$
