• formula is: error/(truevalue-error)*100
  so 100/(1000-100)*100==>100/900*100
  ans 11 1/9

• let legally 1000g costs 20 rupees
  => cost of 1 gm = 1000/20 = 50 rupees
  now, illegally he gets 20 rupees for 900gm
  => cost of 1 gm now = 900/20 = 45
  
  So his gain on 1 gm = (50-45)/50 * 100 = 10
