Puzzle 149. RIVER CROSSING |
|
|
Five men and five boys have to cross the Mississippi River to attend a birthday party. They have only one row boat with them. Because of the 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? More Logic Puzzles |
