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?
Here’s how I did it in 17 steps. Can you do it faster? Let me know in the comments.

What 5-digit number satisfies the following requirements?
1. No zeroes 2. First two digits are the same 3. Fourth digit is twice the first 4. Last digit is twice the third 5. Sum of all digits is 18
33264.
There are several ways of solving this. One way is to represent each spot with a letter, A – E.
Then you have these equations:
A = B D = 2 * A E = 2 * C A + B + C + D + E = 18
By simplifying, you get:
4 * A + 3 * C = 18
Plug in values for A and C to find that A = 3 C = 2.
