Crossing The Bridge Riddle
There are two villages separated with a river. Each day, four people cross the river through a bridge to work on the other side and earn for their families. On one night when they were returning from work, they noticed that the bridge was about to collapse. Now all of them wanted to cross the bridge before it collapsed as no one wanted to be stuck on that end without their families.
They had just one torch with them and since it was the night time, they could not see without it. The bridge had become weak and it could only accommodate two people at a time. It was going to collapse in just 17 minutes.
The four people took different times to cross the bridge. First one took only a minute, second one took 2 minutes, third one took 5 minutes and the last one took 10 minutes.
How would all of them have managed to cross the bridge in time?

How would all of them have managed to cross the bridge in time?
Hint:
Let us denote the four people with A, B, C and D.
A takes 1 minute to cross, B takes 2, C takes 5 and D takes 10.
A and B cross first spending 2 minutes.
A comes back with torch taking 1 minute.
C and D cross taking 10 minutes.
B comes back with torch taking 2 minutes.
Finally, A and B cross the bridge taking 2 minutes.
2 + 1 + 10 + 2 + 2 = 17 minutes
Thus, this is the way they all managed to cross that bridge that night. Did you answer this riddle correctly?

Sailing On The Ocean
Once there was a man and his wife and son. They were out sailing on the ocean when they got ship wrecked on an island. There was little on the island, few coconuts, small amount of clean water, and some pineapple. There were also quite a few pelicans, which the man thought was strange cause there was so little food on the island. Well one day his son died. They were devastated. The man and his wife tried to survive by eating the pineapples and trying to catch a pelican but never could catch one. When the man was close to death his wife had brought him some meat from a pelican that she had caught. He loved it and that saved his life. He was rescued by a helicopter and brought back to his city without his wife cause she had died before. So one day back in the city he went into a bar and he ordered a pelican sandwich to remind him of his wife. He took one bite and he went outside and shot himself. Why did he kill himself?
Hint:
He took one bite of it but it was not the same meat that his wife had given to him on the island. He realized that the meat she had given him on the island was really her dead son. So he went out and killed himself because he couldn't live with himself after he ate his own son. Did you answer this riddle correctly?
