1. The cost price of 10 articles is equal to the selling price of 9 articles. find the profit percent.
a. 101/9 % b. 100/9 % c. 102/9 % d. 103/9 %

• b. 100/9 %
  If cost price of each article=x, then CP of 9 article=9x and CP of 10 article=10x=SP of 9 article.
  So profit %=(10x-9x)*100/9x=100/9

• let
  (10)cp=9(sp)
  cp= 9(sp)/10
  assume sp is 100 ( we assume 100 because in dominator we have 10 if there we have like
  6 we assumed it 60)
  now cp= 900/10=>90
  cp =90 and sp= 100 here we have gap of 10 (100-90)
  now profit %=10/90*100=100/9

• Ans: 100/9 %
  Let Cost Price be x and selling price be y
  Then given that cost price of 10 articles is equal to the selling price of 9 articles
  That means 10x=9y
  Y= 10x/9
  Profit percent = (( selling price – cost price )/cost price ) * 100
  = 100/9 %
