  Five men and five boys have to cross over the Thames River to attend a birthday party. They have only one small boat with them. Due to small size of the row boat, the boat can not carry more than one man, or more than two boys. Thus, a man riding with a boy would not be possible. What would be the least number of boat trips that would take everyone to the other shore?
  
  Total 27 trips with small boat.... Confused? look at here....
  
  

  Trip1. 2 Boys row across.
  
  

  Trip2. 1 Boy comes back.
