the selling price of article sold at loss.​

Answer 1

Answer:

For the first article,

SP=RsS

Given, Profit=25 %

=>

CP

SP−CP

×100=25

=>

CP1

S−CP1

×100=25

=>S−CP1=0.25CP1

=>1.25CP1=S

=>CP1=

1.25

S

=

5

4S

For the second article,

SP=S

Given, Loss=25 %

=>

CP

CP−SP

×100=25

=>

CP2

CP2−S

×100=25

=>CP2−S=0.25CP2

=>0.75CP2=S

=>CP2=

0.75

S

So, Total SP of the two articles =RsS+RsS=Rs2S

Total CP the two articles =Rs
