1. Explain a database in three sentences to your eight-year-old nephew.

2. How many times a day do a clock’s hands overlap?

3. You have to get from point A to point B. You don’t know if you can get there. What would you do?

4. Imagine you have a closet full of shirts. It’s very hard to find a
shirt. So what can you do to organise your shirts for easy retrieval?

5. In a country in which people only want boys, every family continues to
have children until they have a boy. if they have a girl, they have
another child. if they have a boy, they stop. what is the proportion of
boys to girls in the country?

6. You are at a party with a friend and 10 people are present including
you and the friend. your friend makes you a wager that for every person
you find that has the same birthday as you, you get $1; for every
person he finds that does not have the same birthday as you, he gets
$2. would you accept the wager?

7. How many piano tuners are there in the entire world?

8. You have eight balls all of the same size. Seven of them weigh the
same, and one of them weighs slightly more. How can you find the ball
that is heavier by using a balance and only two weighings?

9. You have five pirates, ranked from five to one in descending order. The
top pirate has the right to propose how 100 gold coins should be
divided among them. But the others get to vote on his plan, and if
fewer than half agree with him, he gets killed. How should he allocate
the gold in order to maximise his share but live to enjoy it? (Hint:
One pirate ends up with 98% of the gold.)

10. One train leaves Los Angeles at 15mph heading for New York. Another
train leaves from New York at 20mph heading for Los Angeles on the same
track. If a bird, flying at 25mph, leaves from Los Angeles at the same
time as the train and flies back and forth between the two trains until
they collide, how far will the bird have travelled?

11. Pairs of primes separated by a single number are called prime pairs.
Examples are 17 and 19. Prove that the number between a prime pair is
always divisible by six (assuming both numbers in the pair are greater
than six). Now prove that there are no “prime triples”.

12. Imagine you are standing in front of a mirror, facing it. Raise your
left hand. Raise your right hand. Look at your reflection. When you
raise your left hand your reflection raises what appears to be his
right hand. But when you tilt your head up, your reflection does too,
and does not appear to tilt his/her head down. Why is it that the
mirror appears to reverse left and right, but not up and down?

13. How would you build an alarm clock for deaf people?

14. If Microsoft told you we were willing to invest $5-million in a start-up of your choice, what business would you start? Why?
