This room has no doors, no windows and no other hole large enough for the prisoner to escape via. He has no tools, he has no assistance. He does have a table and a chair in the centre of the room. The room is quite large, walls are two foot thick.
How can the prisoner escape?
Hint: This is a trick that you'll never guess, but is something you'll remember for a very long time.
First he rubs his finger on the table until it is sore, cuts the table in half with the saw. Puts the two halves of the table together to make it whole. Climbs in the hole and shouts until he is hoarse. Climbs on the horse and rides away.
Which of these is correct:
Six and six IS eleven or six and six ARE eleven?
Hint: Is this a test of your English?

My bath has two taps and a plug hole.
The cold tap on its own fills the bath in 8 minutes, the hot one in 8 minutes. The plug hole can drain the bath in 6 minutes with the taps off.
How long will the bath take to fill if I leave both taps on with the plug left out?
Hint: How many baths could be filled in 24 minutes?
Answer: 12 minutes.
In 24 minutes, the cold tap could fill 3 baths, the hot tap could fill 3 baths and the plug could drain 4 baths.
Therefore, in 24 minutes, we have 3 + 3 - 4 baths full = 2 baths.
Therefore each bath would take 12 minutes to fill.
