a seller by means of a false weight defrauds 10% in buying goods and also defrauds 10% in selling.his gain percent is how much?

• let suppose sell 1 kg = 1000gm .
  when he buy 1 kg he cheat 10 %(given).
  i.e actually buy 1100gm.
  now , when he sell 1 kg he cheat 10%(given).
  i.e sell only 900gm.
  now please see in the que it also say that ,
  the amount 1 kg is same when he buy and when he sell .
  i.e he trade at the same price.(i.e use profit % formula if wieght is known)
  profit % = good left/goods sold * 100.
  gain % = (1100gm - 900gm)/900gm *100.
  gain % = 22.22%(ans)

• profit=10+10+(10*10)/100
  
  =21% profit

• 100......................110;
  100.......................90;
  ------------------------------
  profit ..................20 on 90;
  Therefore profit % =20*90/100 = 22.22%
