At a bar in Bangkok – I don’t remember the name – a bar owner sometimes gives a riddle to there guests and if you are right, you win a beer.
So I remember to one of this riddle. I had to answer within a half minute (and quicker than the other guests):
“If you wrote all of the numbers from 300 to 400 on a piece of paper, how many times you have written the number 3?”
God thanks I wasn’t drunk – and I won the beer
Do you know the result????? :p
