text: The riddle of the water tank or the tank issue is one of the content in the book " The nine chapters on mathematical art " one of the oldest books math China, dating back to the period of Zhou Dynasty.
  
  Riddle:
  We have a water tank of 48 m3 capacity with two filling pipes and drain .
  The first filler pipe open one would take 12 hours to fill the tank .
