The following puzzle was posted on the internet with the claim that only one person in a 1000 could find the correct answer.
This ratio looked very strange to me, so could you please vote here?
Once you find an answer that can stand a logical test, then vote for "yes".
Notice the problem has 2 answers. Either one can pass a logical test and they are both correct.
Please do not post your solution, just vote.
1+4=5
2+5=12
3+6=21
8+11=?
The solution will be posted after the poll is over.
