Logic and Lateral Thinking

Picture of mouse in a cardboard maze. It has eaten its way through the walls directly to the cheese.Picture of a Maze with a line drawn directly from one side to the other with the word Parkour written underneathSometimes we assume too much when we think.  We place restrictions on our thinking that the ‘rules’ never made explicit.

The mouse in the illustration was under no obligation to follow the maze.  I also have a T-Shirt with the picture at right.  I guess free runners have the skills to leap over tall buildings and …


This page will be used for serious logic questions as well as the more light-hearted and lateral question as well.


Transferring Liquid Between Beakers

Two beakers with different coloured liquids in themYou have a beaker containing exactly 200 mL of pure water.  You have a second beaker containing exactly 200 mL of pure alcohol.

They can mix, but they are chemically different.

You take one teaspoonful of water and drop it in the beaker containing alcohol.  You now take one teaspoonful of the mixture and return it to the beaker of water.

Now, is there more alcohol in the water, or more water in the alcohol?

Answer: Answer to the liquid transfer puzzle.

The Local Barber

Young adult male getting hair cutIn a small country town everyone has regular haircuts.

All haircuts are carried out within the township.  Some people prefer always to cut their own hair.  The others always get the village barber to cut their hair.  The village barber also lives in the town.

Now, just to make the conditions perfectly clear ... no one, except the barber, ever cuts anyone else's hair. And none of the men who cut their own hair ever let the barber touch it.

Question: Who cuts the barber's hair?

Answer: Answer to the village barber question

I would describe Graeme as one of the best tutors I ever had. During my school years I spent some time attending one of the major tutoring organizations in town and I found it was difficult for the tutors to spend the time needed to assist me with problem solving due to the class size. My mother rang a private tutor in the phone book who gave her Graeme’s phone number as he specialized in tutoring high school students and was a teacher who used to work at my school. He offered a tutoring service at convenient times which suited our busy life style. The one-on-one service that Graeme provides was what I needed and I saw improvements straight away with my exam results. This made my parents very happy and I found a new confidence in approaching exams. I have since left school but have stayed in contact with Graeme and he has provided me with terrific practical suggestions in preparing for interviews. I would not hesitate in recommending Graeme as a great teacher.
