1 Number of tractors on Sun May 02, 2010 10:00 pm

There are 3 persons X, Y and Z. On some day, X lent tractors to Y and Z as
many as they had. After a month Y gave as many tractors to X and Z as many as
they have. After a month Z did the same thing. At the end of this transaction each
one of them had 24.
Find the tractors each originally had?
