Brain Teaser SMS



A boat has a ladder that has six rungs. Each rung is one foot apart. The bottom rung is one foot from the water. The tide rises at 12 inches every 15 minutes. High tide peaks in one hour.

When the tide is at its highest, how many rungs are under water?

Answer: None. The boat is floating on the water, so as the tide rises, so does the ladder.
