so it went down from 300000 to 225000, namely 75000.

now, if we take 300000 to be the 100%, what is 75000 off of it in percentage?

[tex]\bf \begin{array}{ccll} amount&\%\\ \text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\ 300000&100\\ 75000&x \end{array}\implies \cfrac{300000}{75000}=\cfrac{100}{x}\implies \cfrac{4}{1}=\cfrac{100}{x}\\\\\\ x=\cfrac{1\cdot 100}{4}[/tex]
