Mr. X sold an article at 10% loss. Had he bought it for 20% less and sold it for $77 more he would have gained 30%. Find its Cost Price?
A. $500
B. $650
C. $550
D. $600
E. None of these

• Let CP is x
  Sp1=(100-10/100)*x=9x/10
  Sp2 at 20% loss=(100-20/100)*x
  =80x/100=4x/5
  Sp2 at gain 30%=(100+30/100)*4x/5
  =26x/25
  26x/25-9x/10=77
  x=550

• cp1 = 100%
  sp1 = 90%(at 10% loss)
  cp2 = 80%
  sp2 = 104% (130% of 80)
  (104-90)% = 77
  14% = 77
  then 100% = (77*100)/14 = 550

• let y=cost of article
  
  y=100%
  
  p=80%
  
  77/p=30%
  
  p=77/30%
  
  p=256.67
  
  80% => 256.67
  100% => 256.67/80*100
  Therefore, y=320.83
  cost= Rs 320.83
