Buckets of Water
There is a fire in a building. They need exactly 7 quarts of water to put it out (don't worry about why). A man goes out to the river with the only two buckets they have: a 5 quart bucket and a 3 quart bucket. The buckets are not see-through and they have no level indicator markings. How does the man get exactly 7 quarts of water?
Answer
The man takes the 5 quart bucket and fills it up. Then he dumps the water into the 3 quart bucket. Then he dumps the 3 quart bucket back in the river. He then dumps what's left in the 5 quart bucket (2 quarts) into the 3 quart bucket. Then he fills up the 5 quart bucket. Both buckets together now total 7 quarts: 5 quarts in the 5 quart bucket and 2 quarts in the 3 quart bucket.Hide Answer Show Answer
