@TheQuantZone Pick k gold bars from Bk bag so we have 5 bags so in total we take out 15 gold bars 1 from B 1 , 2 from B2 , ........5 from B5 now we keep all the 15 gold bars on the scale so if all of them are real the reading should be 150lbs which it wouldnt the actual reading would comeout as 150-2k so lets say if the reading is 144lbs it means that the third bag was the fake one. thank you
