Riddles from Tony

1. A man is trapped in a room. The room has only two possible exits: two doors. Through the first door there is a room constructed from a magnifying glass. The blazing hot sun instantly fries anything or anyone that enters. Through the second door there is a fire breathing dragon. How does the man escape?

2. Gretchen and Henry wanted to buy a house, and finally found one with a beautifully landscaped yard, plenty of bedrooms, and a beautiful tree out front. They asked the owner how old the house was, and this was his reply.

"I planted that tree when the house was built. It was 7 feet tall at the time. It has grown 3 feet each year, and at the end of this past full year, it was four times its original."

"But how old is the house?" asked Henry.

Gretchen said, "He just told us."

So, how old is the house?

3. There are five doors, one leads to the exit, the others lead to traps. They are in line. The clues tell you which position the doors are in and where the door to freedom is. All the clues are true. Each door has a clue written on it. The clues read:

The blue door: This door is two spots away from the door to freedom.
The red door: This door is at the far right, and is two spots away from the blue door.
The purple door: This door is not next to the door to freedom.
The green door: This door is left of the blue door.
The orange door: This door is not next to the red or blue doors.

Which door leads to freedom?
