Some articles were bought at 6 articles for Rs. 5 and sold at 5 articles for Rs. 6. Find the gain percentage.

• answer is 44 % gain
  explanation:-
  given:
  CP of 6 articles=Rs .5
  SP of 5 articles=Rs. 6
  
  therefore, CP of 5 articles=(5/6)*5=25/6 (just to make equal articles both side 5 for SP and CP)
  
  CP of 1 article=5/6
  SP of 1 article=6/5
  
  therefore
  gain%=(gain/CP) * 100%
  but, gain=SP-CP=6/5-5/6=11/30
  
  and , gain/CP=(11/30) * (6/5)=11/25
  thereore, gain%=(11/25) * 100%=44%

• cp=6*5=30
  sp=5*6=30
  gain=sp-cp/cp*100
  =(6/30)*100
  =20%
