If you think you can think, think again. Yes, think...to answer some very easy LOGICAL PUZZLES. For one thing you can be sure of, all these puzzles have relevant solutions as well. Check how relevant do you think. Put on your thinking caps, and ... .... ... (what are you waiting for) think.
1. During a family get-together, there were the following people: one grandfather, one grandmother, two fathers, two mothers, four children, three grandchildren, one brother, two sisters, two sons, two daughters, one father-in-law, one mother-in-law, and one daughter-in-law. But not as many people attended as the sentence seems them to. How many family members in all were there, and who were they?
2. A winery owner passed away. In his will, he left 21 barrels (seven of which are filled with wine, seven of which are half full, and seven of which are empty) to his three sons. However, the wine and barrels must be divided in a way so that each son has the same number of full barrels, the same number of half-filled barrels, and the same number of empty barrels. Unfortunately, there're no measuring devices handy. How can the barrels and wine be evenly divided?
3. A man goes out for a walk. He walks south one mile, east one mile, and north one mile, and ends up in the same place he started. He didn't start out at the north pole -- so where did he?
4. A mountain goat attempts to scale a cliff sixty feet high. Every minute, the goat bounds upward three feet but slips back two. How long does it take for the goat to reach the top?
5. You have three boxes of fruit. One contains just apples, one contains just oranges, and one contains a mixture of both. Each box is labeled -- one says "apples," one says "oranges," and one says "apples and oranges." However, it is known that none of the boxes are labeled correctly. How can you label the boxes correctly if you are only allowed to take and look at just one piece of fruit from just one of the boxes?
6. Why is it better to have round manhole covers than square ones?
7. A set of three light switches are located in the first floor of a building. Only one of them turns on a light on the second floor. The other two switches do nothing. If you can only go up the stairs one time, and you can't see the second floor light from the first floor, how can you be sure which switch turns on the second floor light?
8. Can you place six X's on a Tic Tac Toe board without making three-in-a-row in any direction?
9. A high school has a strange principal. On the first day, he has his students perform an odd opening day ceremony: There are one thousand lockers and one thousand students in the school. The principal asks the first student to go to every locker and open it. Then he has the second student go to every second locker and close it. The third goes to every third locker and, if it is closed, he opens it, and if it is open, he closes it. The fourth student does this to every fourth locker, and so on. After the process is completed with the thousandth student, how many lockers are open?
10. Two trains travel toward each other on the same track, beginning 100 miles apart. One train travels at 40 miles per hour; the other travels at 60 miles an hour. A bird starts flight at the same location as the faster train, flying at a speed of 90 miles per hour. When it reaches the slower train, it turns around, flying the other direction at the same speed. When it reaches the faster train again, it turns around -- and so on. When the trains collide, how far will the bird have flown?
