Question

By selling an article for Rs. $225$, a shopkeeper loses Rs. $25\%$. Find his gain or loss percent, if he sells the article for Rs. $360$.

Answer 1

$CP=Rsx$

$SP=Rs225$

$loss=25\%$

$\frac{x-225}{x}=\frac{25}{100}$

$⟹100x-22500=25x$

$⟹75x=22500$

$⟹x=300$

Now, $SP=360$

$profit\%=\frac{360-300}{300}\times 100=\frac{60}{3}=20\%$
