Riddle:

A box of hardware contains nuts and bolts.  The bolts account for 25 percent of the number of items in the box.  What percentage are the bolts of the entire box.

Answer:

20 percent. For example, there are 10 bolts.  Since the number of bolts is 25 percent of the number of items, there must be 40 nuts. The total number of items = 10 bolts + 40 nuts = 50.  So, 10/50 = 1/5 = 20%.

Riddle:

If you have two hourglasses -- one four-minute timer and one seven-minute timer, how can you measure nine minutes?

Answer:

Turn over both hourglasses at once. When the four-minute hourglass runs out, turn it over. When the seven-minute hourglass runs out, turn it over. When the four-minute timer runs out this time (eight minutes have elapsed), the seven-minute hourglass has been running for one minute. Now turn over the seven minute timer back over. When the timer runs out, nine minutes have elapsed.
