A Puzzle
A census taker approaches a woman leaning on her gate and asks about the ages of her children. She says, "I have three children and the product of their ages is seventy–two. The sum of their ages is the number on this gate." The census taker does some calculation and claims not to have enough information. The woman enters her house, but before slamming the door tells the census taker, "I have to see to my eldest child who is in bed with measles." The census taker departs, satisfied.
What are the ages of the three children?

Puzzle:
ReplyDeleteYou are on a path and approach two doors. One door leads to death, the other continues the path. The doors are guarded by two men. One can only tell the truth while the other can only lie. You can ask one of the men only one question. What question do you ask to know which door does not lead to death?
The question is: "What would the other guard say if I asked him which door continues along the path?" No matter who we ask we have the same reply, and the opposite is the correct door. This makes it so that in both cases the liar is involved in the reply, and the answer is always false.
ReplyDeleteThe 3 ages are 8,3 and 3 ,the number of the gate is 14.
