After allowing a discount of 11.11%, a trader still makes a gain of 14.28%. At how many per cent above the cost price does he mark on his goods?
Option
1) 28.56%
2) 35%
3) 22.22%
4) None of these

• let us consider cost price to be Rs.100
  thus,S.P. will be Rs.114.28 (i.e. 100+14.28)
  now discount=11.11%
  let marked price be Rs.x
  thus,(100-11.11)=88.89% of x =Rs.114.28
  x=(114.28 * 100)/ 88.89
  =128.56%
  thus marked price is 28.56% above original cost price..
  the ans is 1)28.56%

• ans: 22.22%
  let M.P=100;
  s.p after allowing 11.11% discount= 100*(100-11.11)/100 =88.89
  c.p = 100*s.p/(100+gain%) => (100*88.89)/100+14.28 =77.504
  % of m.p above c.p = ((m.p-c.p)/m.p)*100 = (100-77.504/100)*100 =22.22%

• 28.56% is correct

• let M.P=100;
  
  s.p after allowing 11.11% discount= 100*(100-11.11)/100 =88.89
  
  c.p = 100*s.p/(100+gain%) => (100*88.89)/100+14.28 =77.78
  
  DIFFERNCE IN MP & CP= 100-77.78 =22.22
  
  
  % of m.p above c.p = ((m.p-c.p)/m.p)*100 = 22.22/77.78*100 =28.56%
