1 and 2 cross = 2 minutes
1 returns = 1 minute
5 and 10 cross = 10 minutes
2 returns = 2 minutes
2 and 1 cross = 2 minutes

Total = 17 minutes

rofl..

You have 4 people on one side of a bridge. They have 1 flashlight and nobody can cross without the flashlight. The bridge will hold only 2 people at a time. One person takes 1 minute to cross, another takes 2 minutes, another takes 5 minutes and the last person takes 10 minutes.

How do you get they all get to the other side of the bridge without going over 17 minutes?

So they don't get their meal??
How silly is that when they have lots of food to cook.
If they had no food at all they may have tried harder to figure it out... or maybe their brain just can't think...

What was the riddle and the answer to the 3 switches question?

there's an room with one light. outside the light are three switches, and only one of them turns the light off and on. The door to the room is closed, you can't see any light from the room with the door closed (even if the switch is on), and you only get to open the door and enter the room one time. How can you be sure of what switch turns the light on and off?

Answer: turn on switch #1 for a long time, heating up the bulb. then turn #1 off, IMMEDIATELY turn switch #2 on, then open the door. If the light is on, it's switch #2. If it's off, touch the bulb. if the bulb is warm, it's switch #1 (since that switch would have just been tuned off, the light would still be warm). If it's cool, it's switch #3.
