RIVER CROSSING PUZZLE -1

CANNIBALS AND MISSIONARIES

Three missionaries and three cannibals want to get to the other side of a river. There is a small boat, which can fit only two. To prevent a tragedy, there can never be more cannibals than missionaries together.

How could all of them get safely across the river?

Solution: 

1 cannibal and 1 missionary there, missionary back.

2 cannibals there, 1 cannibal back.

2 missionaries there, 1 missionary and 1 cannibal back.

2 missionaries there, 1 cannibal back. 

This one cannibal takes the remaining cannibals to the other side.
