6% increase

Explanation:

Answer 2

well, the amount is 265 - 250 = 15, so if we take 250(origin amount) as the 100%, what is 15 off of it as percentage?

`\begin{array}{ccll} Amount&\%\\ \cline{1-2} 250 & 100\\ 15& x \end{array} \implies \cfrac{250}{15}~~=~~\cfrac{100}{x} \\\\\\ \cfrac{50}{3} ~~=~~ \cfrac{100}{x}\implies 50x=300\implies x=\cfrac{300}{50}\implies x=6`
