Riddle: There are 3 missionaries and 3 cannibals that need to cross a river. There is only 1 way across the river and that is by boat. There is only 1 boat and only 2 people at a time may cross the river in the boat. You cannot have more cannibals than missionaries on one side of the river or else the cannibals will eat the missionaries and you fail. How can you get all 3 missionaries and all 3 cannibals across the river in one piece?
Hint: The cannibals cannot eat each other

Missionaries And Cannibals Solution
Answer: This is the 12 step process for completing this brain corker. I will call the starting place side A and the destination side B.
1) Send 1 cannibal and 1 missionary across the river.
2) Drop off the cannibal at side B and send back the missionary to side A.
3) Drop off the missionary at side A and send over 2 cannibals to side B.
4)Drop 1 off at side B and then go back to side A.
5) Drop off the cannibal at Side A and send over 2 missionaries.
6) Drop 1 off at side B, then pick up a cannibal from side B and go back to side A.
7) Drop off the cannibal at side A and pick up a missionary from Side.
8) Drop off both missionaries at side B and then send 1 cannibal from side B back.
9) Pick up a cannibal from side A and take him to side B.
10) Drop 1 off at side B and go back to side A.
11) Pick up the final cannibal from side A and take him over to side B.
12) Drop off both cannibals.
And that's all there to it!
A lot of people think it's impossible but it's really simple when you use the right logic.

In the Missionaries and Cannibals problem. Three missionaries and three cannibals must cross a river using a boat which can carry at most two people, under the constraint that, for both banks and the boat, if there are missionaries present on the bank (or the boat), they cannot be outnumbered by cannibals (if they were, the cannibals would eat the missionaries). 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.
