Actually each has 24 at the end.
In the last transaction Z gave its tractors to Y and X i.e, X and Y's amount has been doubled
X=12; Y=12; Z= X+Y+24 =48;
and now the transaction happened by Y
similarly
X=6; Z=24; Y= X+Z+12 =42;
then the transaction happened by X
Y=21; Z=12; X= Y+Z+6= 39;
So, at the beginning X has 39, Y has 21, Z has 12.
