This forum is all about riddles that we know, and want to share then here. Here is one.
You and 3 of your friends are at the top of a tall mountain. There is a long bridge right in front of you that leads to the mainland.
But there are some problems.
1. You and your friends should reach the other side of the bridge in 17 exact minutes, or the bridge will collapse.
2a. You take 1 minute to cross the bridge.
2b. Your 1st friend, Mike, takes 2 minutes.
2c. Your 2nd friend, Anna, takes 5 minutes.
2d. Your 3rd friend, Josh, takes 10 minutes.
3. The bridge can only carry 1 or 2 people at a time.
4. The night is very dark, and if one of you is not careful, you might step on a broken plank and fall down the bridge. But you have a Lantern that all of you can see in the dark, but you can't reach the other side of the bridge without it. (For example, if you crossed the bridge with Mike and the Lantern, Anna and Josh can't cross the bridge because they don't have the Lantern.)
How will you reach the other side of the bridge in time?
