Riddle:
Jack has 8 bricks, 7 of them weigh the same but one is slightly heavier. Using a balance scale, how can Jack find the heavier brick in two weighings?
Answer: First, he splits them into piles of 3, 3, and 2 bricks.
Then, he weighs both groups of 3 with each other. If they balance he knows the brick is one of the 2 unweighed bricks and he can weigh them to find the heavier one.
If the stacks of 3 bricks do not balance, he will weigh 2 of the 3 bricks.
If they balance he will know the brick left unweighed is heavier, or if they do not balance, he will find the heavier one.

Three working women have different careers. If only one of statements 1, 2 and 3 are true, can you tell whether or not Mary is a nurse? 1. This statement is only true if statement 5 is false. 2. This statement is true if statements 4 or 5, or both 4 and 5 are true. 3. This statement is false only if both statements 6 and 1 are true. 4. Mary is a nurse 5. Karen is an artist. 6. Sarah is a photographer.
Answer: Mary is not a nurse. The way to solve this riddle is to consider statements 4, 5, and 6 and create a chart of all possible true and false answers. Next, fill in the chart according to statements 1 through 3. You will discover that there is only one line where only one of the statements one, two, and three are true. Thus, it is determined that: Statements 4 and 5 are false and statement 6 is true.
