Question

if the cost price is 80%of the selling price what is the profit percent ​

Answer 1

Let , selling price = 100

So , cost price = 80

Therefore , Profit = 20

And

$\red{\underline{ \fbox{ \orange{\mathtt{Profit \: percentage = \frac{profit \: price}{cost \: price } \times 100}}}}}$

$\sf = \frac{ \cancel{20}}{ \cancel{80}} \times 100 \\ \\ \sf = \frac{1}{ \cancel4} \times \cancel{100} \\ \\ \sf = 25 \: \%$

Hence , the profit percentage is 25 %
