Imagine you are a pilot of a plane. You are going to fly a plane from Northern Maine to Los Angelos, California, which is 3000 miles. It takes 10 hours. You drive to a hotel in LA which is 18 miles from the airport. The next day, you wake up and drive back to the airport which is another 18 miles. You fly another plane up to Vancouver, Canada which is 700 miles. When you arrive in Canada, you go into the employees lounge and you sleep at the airport that night. The next day, you fly a long trip to Sydney, Australia which is 10,000 miles. You stay in Sydney for 3 days, and then you fly all the way back to Northern Maine, where your home is. The flight is 12,000 miles. How may miles did you go in total and how old is the pilot?

What question do you ask all day, but the answer is always different.

Mr. House would like to visit his old friend Mr. Street, who is living in the main street of a small village. The main steet has 50 houses divided into two blocks and numbered from 1 to 20 and 21 to 50. Since Mr. House has forgotten the number, he asks it from a passer-by, who replies "Just try to guess it." Mr. House likes playing games and asks three questions:

1. In which block is it?
2. Is the number even?
3. Is it a square?

After Mr. House has received the answers, he says: "I'm still doubting, but if you'll tell me whether the digit 4 is in the number, I will know the answer!". Then Mr. House runs to the building in which he thinks his friend is living. He rings, a man opens the door and it turns out that he's wrong. The man starts laughing and tells Mr. House: "Your advisor is the biggest liar of the whole village. He never speaks the truth!". Mr. House thinks for a moment and says "Thanks, now I know the real address of Mr. Street".
What is the adress of Mr. Street?
