On a game show there are three
closed doors - one hides a car and the
other two conceal a goat. The contestant
selects a door, which remains closed,
and the host, knowing where the car is
hidden, reveals a goat behind one of the
remaining two doors. The contestant is
then given the option to switch doors or
stay with the one they originally selected.
What should the contestant do to have
the best chance of winning the car?
Show the answer Direct link
The contestant should switch doors,
which doubles the chance of winning the
car. Initially there is a 2/3 chance of
picking a goat, but once the other goat is

gives the contestant a better chance of
winning the car. This is known as the

How can you write a date in 5
letters without using any numbers?
Show the answer Direct link
The most popular answer for this teaser
is 'today'. Of course this only works if
you're reading it on that particular date
or if the date is not specified. Another
option is to respond literally with 'a date'.
Lastly, certain dates could be squeezed
into letters using Roman numerals if you
abbreviate the year to 2 numerals. For
example, January 20th, 2011 would be I
XX XI.

Franklin lent Darlene as much
money as she already had, then she
spent $10. The next day, Franklin lent
her as much money as she now had and
again, she spent $10. On the third day
Franklin once again lent her as much
money as she now had and she spent
$10, leaving her broke. How much
money did Darlene start with?
Show the answer Direct link
$8.75
You may have been tempted to guess $30
because $10 is spent three times, but
that would mean she would have had
$60 ($30 lent plus the $30 she already
had), and $50 after spending $10. The
rest of the numbers end up at higher
than zero, so we know it has to be less
than $30. Even starting at $10 leaves
Darlene with $10 on the third day.
Starting with $8.75 works out as follows.

At the market you can buy a cow
for $10, a pig for $1 and 8 hens for $1.
How many animals would you need to
buy to get 100 mixed animals for exactly
$100?
Show the answer Direct link
7 cows, 21 pigs and 72 hens. The trick to
this is finding the combination of cows
and hens with the same cost and
quantity since pigs are already equal.
The magic combination is 7 cows and 72
hens, giving you 79 animals that cost
$79 ($70 + $9). Then you just add 21
pigs to get to 100 animals.

A couple has two children. At least
one of them is a boy. Assuming the
probability of having a boy or girl is 50%,
what is the probability that both children
are boys?
Show the answer Direct link
If you answered 1/2, you're not without
comrades, but the answer is 1/3. This is
because there are only four possible
combinations: Boy-Boy, Boy-Girl, GirlBoy and Girl-Girl. Since we are told one
of the children is a boy (but we don't
know if it's the first or second child), we
can rule out the Girl-Girl combination,
leaving three remaining options. Only
one of those is Boy-Boy, which is a 1/3
chance.

The problem works out to a set of
three equations:
b + c + d = 22
a + c + e = 22
a + b + c + d + e = 30
Solving for c = 14, leaving d = 8 - b and e
= 8 - a. In other words, c must be 14, but
the other two numbers just have to add
up to 8. The requirement that they be
unique rules out 4 + 4, so you're left to
choose from the following combations for
b + d and a + e:
0+8
1+7
