After allowing a discount of 11.11%,a trade still makes a gain of 14.28%.At how much percentage above the cost price does he mark his goods?

• suppose selling price= x;
  after discount selling price will be (x-.1111x)=.8889x=(8/9)x
  gain=14.28%
  so cost=(8/9)x-[(8/9)x*.1428]
  =(8/9)x-(8/63)x
  =(48/63)x
  so the selling price is [x-(48/63)x] = (15/63)x =23.8% more than cost price
