There were 3 persons A, B and C. Each of them had a certain number of tractors. After one month, A gave as many number of tractors he had to B and C. After one month B gave as many number of tractors he had with him to A and C. Similarly, C gave as many number of tractors he had to A and B. If each of the persons now have 24 tractors after all these transactions, how many tractors were each of them having initially?

• Sankara, Solve it by Backtracing method..THis is a logical Question.
  
  
  It's given that at the end, each had 24 tractors (24, 24, 24) i.e. after C gave tractors to A & B as many as they
  had. It means that after getting tractors from C their tractors got doubled. So before C gave them tractors,
  they had 12 tractors each and C had 48 tractors. (12, 12, 48)
  
  
  Similarly, before B gave tractors to A & C, they had 6 & 24 tractors respectively and B had 42 tractors i.e. (6,
  42, 24)
  
  
  Again, before A gave tractors to B & C, they had 21 & 12 tractors respectively and A had 39 tractors i.e. (39,21, 12)
  
  
  THUS< initially A had 39 tractors, B had 21 tractors and C had 12 tractors.

• 24,because ,here initially A,BandC has 24 tractors so each person while tractions they transfer their 24 tractors to the others that is they give as many tractors they have to others i.e 24 tractors
