Problems
Stephen was looking at a photo. Someone asked
him, "Whose picture are you looking at?" He
replied: "I don't have any brother or sister, but
this man's father is my father's son." So, whose
picture was Stephen looking at?
There was a robbery in which a lot of goods were
stolen. The robber(s) left in a truck. It is known
that : (1) Nobody else could have been involved
other than A, B and C. (2) C never commits a
crime without A's participation. (3) B does not
know how to drive. So, is A innocent or guilty?

Problem
The farmer wants to get his goat, wolf and
cabbage to the other side of the river. His boat
isn't very big and it can only carry him and either
his goat, his wolf or his cabbage. Now.....if he
leaves the goat alone with the cabbage, the goat
will gobble up the cabbage. If he leaves the wolf
alone with the goat, the wolf will gobble up the
goat. When the farmer is present, the goat and
cabbage are safe from being gobbled up by their
predators.
How does the farmer manage to get everything
safely to the other side of the river?

Can you think of a picture or a diagram that
might help you understand the problem?
Is there enough information to enable you to find
a solution?
Do you understand all the words used in stating
the problem?
Do you need to ask a question to get the answer?
