What plant becomes the name of a star by removing the first letter, becomes a number without the last letter and becomes a bird if the first and last letters are taken away?
Supposedly this is given as a test in Japan. I have no idea if that’s accurate.
There are 8 people who have to cross the river on a raft.
1. Policeman 2. Thief 3. Father 4. Boy 1 5. Boy 2 6. Mother 7. Girl 1 8. Girl 2
The rules are:
Only two people can cross at a time. Only the adults can operate the raft. The father can’t be with the girls unless the mother is there. The mother can’t be with the boys unless the father is there. The thief can’t remain with anyone unless the policeman is present.
How do you get them all across?
Instead of working it out by hand, here’s a flash version.
Click on the circle to start. Click on a person to put them on the raft and click on the lever to make the raft cross.
54325. Rather than being a mathematical solution, the answer is derived by prepending (putting in front of) the value on the left side of the equation with the previous answer. So for 3 you take 25, the previous answer, and put 3 in front, giving you 325. Then you put 4 in front to get 4325 and lastly, put 5 in front to get 54325.
