I have put this page here for the interest of 'logical' thinking. Solving these puzzles out on paper or in your head can help you program a little better. Even if you don't program, these puzzles are meant to help your logical thinking.

See the bottom of this page for the answers.

Please give a difficult rating to each (using the rating I have below) that you answer telling me if it was difficult or not for you.

Each puzzle will be ranked from easy to hard by the following:

(*) - Easy

(**) - Should take you a minute or two

(***) - You might need to draw this one out on paper

(****) - You are pretty good if you get this one

You are on your way to the market with eight (8) chickens. When you get to the market, the buyer tells you that he will only take all chickens that have the same weight.

Using these scales only twice, how do you find the lighter chicken? (See the answer)

Three men were on a road trip and decided to rent a motel room for the night. The clerk behind the counter said that there was one room left and that it wasn't very good. The three men decided to take it any way, and asked how much. The clerk asked for $30 and the men each paid $10 and went to the room to rest for the night. When the manager came by the office, he asked how much the clerk had charge the three men for that room. The manager said that was to much and gave the clerk $5 to give back to the three men in the morning. The clerk thought for a minute and said to himself, "I don't know how to divide $5 evenly to the three men." So he put $2 in his pocket and gave $1 to each of the men.

If each of the men paid $9 for the room and the clerk had $2 in his pocket, where did the other dollar go? (See the answer)

Do you see the pattern?

Start in the top row, middle col. (place the '1', there)

1. Go right one col.

- if this goes off the table, "drop" to the left most col.

2. Then go up one row

- if this goes out of the table, drop to the bottom row.

3. If you get to a point, where the next pos will be a filled box, or

the next move will put off the table at the top right, drop

down one box from the last number entered.

4. Place the next number there and continue with 1.

Do you see it now?

Zero.

(x-x) = 0, and anything multiplied by zero = zero.
