You have a basket
containing ten apples. You have ten friends, who each desire an apple. You give
each of your friend’s one apple.
Now all your friends
have one apple each, yet there is an apple remaining in the basket.
How?
Puzzle-2:
You have three bags,
each containing two marbles. Bag A contains two white marbles, Bag B contains
two black marbles, and Bag C contains one white marble and one black marble.
You pick a random bag and take out one marble.
It is a white
marble.
What is the
probability that the remaining marble from the same bag is also white?
Puzzle-3:
How many steps are
required to break an m × n sized bar of chocolate into 1 × 1 pieces?
You can break an
existing piece of chocolate horizontally or vertically.
You cannot break two
or more pieces at once (so no cutting through stacks).
Puzzle-4:
A man is stranded on
an island covered in forest.
One day, when the
wind is blowing from the west, lightning strikes the west end of the island and
sets fire to the forest. The fire is very violent, burning everything in its
path, and without intervention the fire will burn the whole island, killing the
man in the process.
There are cliffs around the island, so he cannot jump off.
How can the man
survive the fire? (There are no buckets or any other means to put out the fire)
Puzzle-5:
You are at an
unmarked intersection ... one way is the City of Lies and another way is the
City of Truth.
Citizens of the City of Lies always lie.
Citizens of the City
of Truth always tell the truth.
A citizen of one of
those cities (you don't know which) is at the intersection. What question could
you ask to them to find the way to the City of Truth?
