Question

By selling a bouquet for $Rs322$, a florist gains $15\%$. At what price should he sell, it to gain $25\%$?

Answer 1

Let selling price be $x$

by selling a bouquet for rupees $322$ a florist gains $15$%

So, $322=x+15$%x

$322=100$%x+$15$%x

$322=115$%x

$\begin{array}{c}\left(\frac{115x}{100}\right)=322\\ 115x=\frac{322}{100}\\ x=\frac{3200}{115}\\ x=280\end{array}$

So, selling price is $x=280$

$25$% gain of sellling price $=280+25$% of $280=280+70=350$
