  Shopkeeper gets 50% profit on SP(250) of each article So CP=100*250/150=500/3
  Therefore CP of 120 article=120*500/3=20000
  Article sold without discount=120*1/4=30 their SP=30*250=7500
  Article sold with discount=90, their SP=90*250*0.8=18000
  Total selling price=7500+18000=25500
  % profit=(25500*100/20000)-100=27.5

  CP of each article = 250*100/150 = Rs 500/3
  CP of 4 articles = 2000/3
  SP of 4 articles = 250+3*350*0.8 = Rs 850
  
  profit on Rs 2000/3= 550/3
  
  % profit = 100*550/2000 = 55/2=27.5 %
