Brain Teasers
Honest, Hey?
My name is Grungy. I am an honest person, and I am thinking of one of these numbers: 1, 2, or 3. You may ask me only one yes-no question - I will answer truthfully, and if you choose the right question, you will know which number I am thinking of! If I cannot answer your question, I will simply tell you that I cannot answer it.
So, what question do you need to ask me to determine what number I am thinking of?
So, what question do you need to ask me to determine what number I am thinking of?
Answer
"I am thinking of either 1.5 or 2.5 - is your number greater than mine?"If I answer, "yes", then you know it has to be 3 - because I can't tell if you're thinking of 2.5 or 1.5. If I answer, "no", it has to be 1. If I answer, "I cannot answer that question", then it is two!
If you can think of another answer, good on ya! Feel free to correct this teaser with the new answer. 8-)
