Question

At profit margin of 20% on sale price is equivalent to how many %​

Answer 1

$\tt{If \: the \: profit \: is \: 20 \: on \: sale \: then}$

$\tt{it \: will \: be \: 25 \: on \: cost}$

$\tt{Cost+profit=sales}$

$\tt{Eg. \: Cost=80 , \: profit=20} \\ \tt{then \: selling \: price \: is \: 100}$

$\tt{Ratio \: of \: profit \: to \: cost \: is \: 20/80 \: ie. 1/4}$

$\tt{Ratio \: of \: profit to \: sales \: is \: 20/100 \: ie. 1/5}$
