Question

when an article is sold at 4/5th of its selling price there is a loss of 28%. what will be profit % when the same article is sold at 6/5th of its selling price.?​

Answer 1

Answer:

8% profit

Step-by-step explanation:

Let the selling price = 100x and buying price=100y

4/5 of selling price =4/5*100x=80x

loss% =100*(100y-80x/100y=28

100y-80x=28y

72y=80x

100y=100*80x/72=8000x/72=1000x/9------------(1)

6/5 of selling price =6/5*100x=120x

profit%=100*(120x-100y)/100y

=100*(120x-1000x/9)/(1000x/9)

=100/9*(1080x-1000x)*9/1000x

=(100*80x*9)/9*1000x

=72000x/9000x

=8%

=
