Ten people land on a deserted island. There they
find lots of coconuts and a monkey. During their
first day they gather coconuts and put them all in
a community pile. After working all day they
decide to sleep and divide them into ten equal
piles the next morning.

That night one castaway wakes up hungry and
decides to take his share early. After dividing up
the coconuts he finds he is one coconut short of
ten equal piles. He also notices the monkey
holding one more coconut. So he tries to take the
monkey's coconut to have a total evenly divisible
by 10. However when he tries to take it the
monkey conks him on the head with it and kills
him.

Later another castaway wakes up hungry and
decides to take his share early. On the way to the
coconuts he finds the body of the first castaway,
which pleases him because he will now be entitled
to 1/9 of the total pile. After dividing them up into
nine piles he is again one coconut short and tries
to take the monkey's slightly bloodied coconut.
The monkey conks the second man on the head
and kills him.

One by one each of the remaining castaways goes
through the same process, until the 10th person to
wake up gets the entire pile for himself. What is
the smallest number of possible coconuts in the
pile, not counting the monkeys?

have twelve coins. You know that one is fake.
The only thing that distinguishes the fake coin
from the real coins is that its weight is
imperceptibly different. You have a perfectly
balanced scale. The scale only tells you which
side weighs more than the other side.
What is the smallest number of times you must
use the scale in order to always find the fake
coin?

Use only the twelve coins themselves and no
others, no other weights, no cutting coins, no
pencil marks on the scale. etc.
These are modern coins, so the fake coin is not
necessarily lighter.

Presume the worst case scenario, and don't hope
that you will pick the right coin on the first
attempt.

A 120 wire cable has been laid firmly underground
between two telephone exchanges located 10km
apart.

Unfortunately after the cable was laid it was
discovered to be the wrong type, the problem is
the individual wires are not labeled. There is no
visual way of knowing which wire is which and
thus connections at either end is not immediately
possible.

You are a trainee technician and your boss has
asked you to identify and label the wires at both
ends without ripping it all up. You have no
transport and only a battery and light bulb to test
continuity. You do have tape and pen for labeling
the wires.

What is the shortest distance in kilometers you
will need to walk to correctly identify and label
each wire?

The warden meets with 23 new prisoners when
they arrive. He tells them, "You may meet today
and plan a strategy. But after today, you will be in
isolated cells and will have no communication with
one another.

"In the prison is a switch room, which contains
two light switches labeled 1 and 2, each of which
can be in either up or the down position. I am not
telling you their present positions. The switches
are not connected to anything.

"After today, from time to time whenever I feel so
inclined, I will select one prisoner at random and
escort him to the switch room. This prisoner will
select one of the two switches and reverse its
position. He must flip one switch when he visits
the switch room, and may only flip one of the
switches. Then he'll be led back to his cell.

"No one else will be allowed to alter the switches
until I lead the next prisoner into the switch room.
I'm going to choose prisoners at random. I may
choose the same guy three times in a row, or I
may jump around and come back. I will not touch
the switches, if I wanted you dead you would
already be dead.

"Given enough time, everyone will eventually visit
the switch room the same number of times as
everyone else. At any time, anyone may declare
to me, 'We have all visited the switch room.'
"If it is true, then you will all be set free. If it is
false, and somebody has not yet visited the switch
room, you will all die horribly. You will be carefully
monitored, and any attempt to break any of these
rules will result in instant death to all of you"
What is the strategy they come up with so that
they can be free?

Answer
1. Appoint a "scorekeeper" and the other 22 prisoners as "transmitters".
2. When a transmitter enter the switch room for the first time, he will flick switch B ON if he sees it in the OFF position. Alternatively, he will flick switch A if he sees switch B is in the ON position and waits for his next visit. The transmitter's mission is to find ONE opportunity to flick switch B to the ON position. After he completes his mission, he will flick switch A for all subsequent visits. In short, each transmitter's role is to send a signal to the scorekeeper that he has been to the switch room.
3. The scorekeeper's role is to flick off switch B whenever he sees it in the ON position. Each time he flicks off switch B he adds 1 to his score. When he sees switch B is already OFF, he flicks switch A instead and does not add to the score. As soon as he accumulates 22, he reports to the Warden.



Honestly I had to google that.

A king wants his daughter to marry the smartest
of 3 extremely intelligent young princes, and so
the king's wise men devised an intelligence test.

The princes are gathered into a room and seated,
facing one another, and are shown 2 black hats
and 3 white hats. They are blindfolded, and 1 hat
is placed on each of their heads, with the
remaining hats hidden in a different room.

The king tells them that the first prince to deduce
the color of his hat without removing it or looking
at it will marry his daughter. A wrong guess will
mean death. The blindfolds are then removed.
You are one of the princes. You see 2 white hats
on the other prince's heads. After some time you
realize that the other prince's are unable to
deduce the color of their hat, or are unwilling to
guess. What color is your hat?

Note: You know that your competitors are very
intelligent and want nothing more than to marry
the princess. You also know that the king is a man
of his word, and he has said that the test is a fair
test of intelligence and bravery.
