(#M40152063) BOOK QUESTION the question of transport Keep an EYE

Twelve soldiers had to get to a place twenty miles distant with the quickest possible dispatch, and all had to arrive at exactly the same time. They requisitioned the services of a man with a small car. "I can do twenty miles an hour," he said, "but I cannot carry more than four men at a time. At what rate can you walk?" "All of us can do a steady four miles an hour," they replied. "Very well," exclaimed the driver, "then I will go ahead with four men, drop them somewhere on the road to walk, then return and pick up four more (who will be somewhere on the road), drop them also, and return for the last four. So all you have to do is to keep walking while you are on your feet, and I will do the res t." They started at noon. What was the exact time that they all arrived together?

(#M40151890) BOOKS QUESTION hat on the head Keep an EYE

After losing the "Spot on the Forehead" contest, the two defeated Puzzle Masters complained that the winner had made a slight pause before raising his hand, thus derailing their deductive reasoning train of thought. And so the Grand Master vowed to set up a truly fair test to reveal the best logician amongst them.
He showed the three men 5 hats - two white and three black. Then he turned off the lights in the room and put a hat on each Puzzle Master's head. After that the old sage hid the remaining two hats, but before he could turn the lights on, one of the Masters, as chance would have it, the winner of the previous contest, announced the color of his hat. And he was right once again.
What color was his hat? What could have been his reasoning?

(#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??
