When C gives A & B the number of tractors each of them have and all have 24 tractors each.
.'. A had 24/2=12 and B had 24/2=12 tractors with them and C had 24 + (12+12) = 48 tractors.
----------------------------------------------------------------------------------------------------------------------------------------------
When B gives A & C the number of tractors each of them have
.'. A had 12/2=6 and C had 48/2=24 tractors and B had 12 + (6+24) = 42 tractors.
----------------------------------------------------------------------------------------------------------------------------------------------
When A gives B & C the number of tractors each of them have
.'. B had 42/2=21 and C had 24/2=12 tractors and A had 6 + (21+12) = 39 tractors.
