➤ To Find :-

Gain or loss percentage of the article.............

➤ Formula required :-

➤ Solution :-

First, we should find the profit of the article in numerical form.............

Gain of an article :-

${\tt \longrightarrow 150 - 125}$

${\tt \longrightarrow Rs \: \: 25}$

Gain percent of article :-

${\tt \longrightarrow \dfrac{25}{125} \times 100}$

${\tt \longrightarrow \cancel\dfrac{25}{125} \times 100 = \dfrac{1}{5} \times 100}$

${\tt \longrightarrow \dfrac{1 \times 100}{5} = \dfrac{100}{5}}$

${\tt \longrightarrow \cancel\dfrac{100}{5} = \boxed{\tt 20 \bf\%}}$

$\Huge\therefore$ The gain percent of the article is 20 ${\bf\%}$.
