#### 1.

Here are two popular solutions to carve a circle into eight sections using three lines.   #### 2.

The letters in the top line are made exclusively of straight lines, whereas the letters in the bottom line are made of at least one curved line.

Once you think outside the box (of the nine dots) the solution is pretty simple.  #### 12.

Place three balls on each side of the scales. If they are balanced, then use the scales for a second time to identify which of the two remaining balls is the heaviest. However, if one set of the three balls is heavier (on the first use of the scales,) take any two of these three balls and set them on the scales. If they are balanced, the third ball is the heaviest. Or, if one of these two balls is heavier, you have your answer.
