THE TRAVELLER
Dirk once travelled in his car when he reached a forked junction. The sign to tell him which
way to go was stolen and thus he was stalled. He remembered that a guy once told him in a pub
about two brothers who lived at that junction. The one brother always lied and the other one
always told the truth. They however only allowed you one question to be asked to one of them.
They were also identical twins so that one never knew which brother lied or which told the truth.
There you have it. Say the sign would have told you the way to Durban and Cape Town.
What would your one question have been to one of the brothers to find your way to Durban
if you had been Dirk?
In the desert
Jessie and Johan were once stranded in a desert. They had a container of eight litres
containing eight litres of water. They also had two empty containers of five and three litres.
They wanted to split the eight litres of water so that each had four litres of water.
How would you go about to share the water by pouring it using the three containers so that
you would end with four litres in the eight litres container and four litres in the five
litre container?
Gold
Suppose you have nine balls. Eight of them are made out of lead and one of them is made out
of gold, but all of them are painted yellow. It is also impossible by weighing them in you
hands to distinguish which ball is made out of gold. However you have a scale that allows
you to put weights on both sides and by balancing them you could then find out which one is
heavier and thus made out of gold.
How would you find the gold ball by just weighting twice? You can put as many balls on the
scale as you like.
Poison
Two guys Bill and Ted each went to the same pub and each ordered a scotch on the rocks.
Each drink contained poison, but Bill and Ted did not know it. Bill quickly downed his drink
and stayed for an hour and talked, before he went home. Ted took a long time to drink his
drink and on his way home he died. Nothing happened to Bill and he stayed alive.
Why did Ted die and Bill stayed alive?
