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?

• 12z,21y,39x cause if x give them twice what they have it would be 24z,42y,and leave 6x then y doubles what z and x have 48z,12y, and 12x then z does the same 24z,24y and 24x so the anwser is 12z,21y,and 39x
