A. The year 2013 uses four different digits. When did this last happen?

B. The digits in 2013 form a sequence (0, 1, 2, 3). When did this last happen (not necessarily the same digits)?

C. The digits in 2013 form a sequence (0, 1, 2, 3). When will this next happen (not necessarily the same digits)?

During the recent BrainBashers cipher convention, a Morse code contest took place. The contest consisted of a Morse code transmission where the spaces between the letters and words were missing. Can you find the ten names for pet cats?

Luckily, BrainBashers has provided you with a listing of the Morse code characters. Good luck!

Below are five book titles.

Each title has had the spaces replaced with extra letters, plus extra letters at the end.

The number of extra letters added equals the length of the previous word. Punctuation has then been added.

For example:
   BOOK TITLE >> BOOK****TITLE***** >> BOO, KNIGHT. IT LEARNED!

Can you find the titles?

My bath has two taps and a plug hole.

The cold tap on its own fills the bath in 18 minutes, the hot one in 15 minutes.

The plug hole can drain the bath in 10 minutes with the taps off.

How long will the bath take to fill if I leave both taps on with the plug left out?

Using a tap, a seven gallon container and a eleven gallon container, can you measure exactly 9 gallons?

You may empty the containers down the drain.
