Answer 1

Answer:

vote me 5

Step-by-step explanation:

For the first article, 

SP=RsS

Given, Profit=25 %

=>CPSP−CP×100=25

=>CP1S−CP1×100=25

=>S−CP1=0.25CP1

=>1.25CP1=S

=>CP1=1.25S=54S

For the second article, 

SP=S

Given, Loss=25 %

=>CPCP−SP×100=25

=>CP2CP2−S×100=25

=>CP2−S=0.25CP2

=>0.75CP2=S

=>CP2=0.75S=34S

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

Total CP the two articles =Rs54S
