Answer 2

from 25000 to 28000 the difference is 3000.

now, if we take 25000 to be the 100%, what is 3000 off of it in percentage?

$\bf \begin{array}{ccll} amount&\%\\ \cline{1-2} 25000&100\\ 3000&x \end{array}\implies \cfrac{25000}{3000}=\cfrac{100}{x}\implies \cfrac{25}{3}=\cfrac{100}{x} \\\\\\ 25x=300\implies x=\cfrac{300}{25}\implies x=12$
