(#M40151889) BOOK QUESTION red dot blue dot Keep an EYE

Three Masters of Logic wanted to find out who was the wisest amongst them. So they turned to their Grand Master, asking to resolve their dispute.
"Easy," the old sage said. "I will blindfold you and paint either red, or blue dot on each man's forehead. When I take your blindfolds off, if you see at least one red dot, raise your hand. The one, who guesses the color of the dot on his forehead first, wins."
And so it was said, and so it was done. The Grand Master blindfolded the three contestants and painted red dots on every one. When he took their blindfolds off, all three men raised their hands as the rules required, and sat in silence pondering. Finally, one of them said: "I have a red dot on my forehead."
How did he guess?

(#M40151888) BOOK QUESTION a hair rising problem Keep an EYE

prof raju is a very interesting person. i met him and started discussing human hair.
prof raju told that there are about 150000 airs on an average mans head. i disagreed with him.
i told him that no one could have actually come by this figure - who would have patience to actually take a man's head and take the hair and count them!

'no' he argued ' it is enough to count them on one square centimeter of a man's head and knowing this and the size of the hair covered surface , one can easily calculate the total number of hairs on a man's head'

then he popped a question at me.it has also been calculated that a man sheds about 3000 hairs a month. can you tell me the average longevity of each hair on a man's head?

can you guess what the answer is??
