the increase is clearly 40 - 25 = 15.

So if we take 25(origin amount) as the 100%, what's 15 off of it in percentage?


\begin{array}{ccll} Amount&\%\\ \cline{1-2} 25 & 100\\ 15& p \end{array} \implies \cfrac{25}{15}~~=~~\cfrac{100}{p} \\\\\\ \cfrac{5}{3} ~~=~~ \cfrac{100}{p}\implies 5p=300\implies p=\cfrac{300}{5}\implies p=60
