Okay, we have the remaining coins ijkl. use i and j to swapwith f and g. Now swap the positions of cd with j and h, and scale abjh on one side with eicd on the other. This is weight number 2.
Actually, we have remaining coins ijklm
After the first weighting, if the odd coin is in abe, the scale will remain the same as the process affects merely the rest of the same coins. If the odd coin is in f ang g which are taken out, it will be balanced on second weighting. If the odd coin is in cdh, the scale will go opposite,. This covers all the possiboilities of after the first unbalanced weighting
