A poor farmer went to the market to sell some peas and lentils. However, as he had only one sack and didn't want to mix peas and lentils, he poured in the peas first, tied the sack in the middle, and then filled the top portion of the sack with the lentils. At the market a rich innkeeper happened by with his own sack. He wanted to buy the peas, but he did not want the lentils.
Pouring the seed anywhere else but the sacks is considered soiling. Trading sacks is not allowed. The farmer can't cut a hole in his sack.
How would you transfer the peas to the innkeeper's sack, which he wants to keep, without soiling the produce?

This one is my favorite among all trick questions and answers. Imagine yourself driving on a highway on a windy day. Suddenly, you notice some people standing by the side of the road, and you slow down. You learn that the people include your best friend, an ailing old woman, and your dream girl. The ailing woman is dying and requires immediate medical help. Now, you have only one chance to spend a day with your dream girl, and of course you can't leave your best friend behind. So, what would you do in order to help the woman to reach the hospital? Remember that, your car can carry 'ONLY TWO' people (the driver and one passenger).
