1. Three people A,B,C are each given 2 colours, for a total of 6
colors ( blue, green, orange, purple, red & yellow ). In
comparing the colours they received, B makes the following
observation " the number of common letters between the two colours
is one less than the number of A's common letters & one more
than the no. of C's common letters." Find the colours each person
received . ( Can there be more than one answer ?)
2. A pirate ship captures a treasure of 1000 golden coins. The
treasure has to be split among 5 pirates on the ship. These
pirates are a bit too much concious of their status. the booty
will be shared in order of their rank 1,2,3,4 & 5. The pirates
have the following 3 characteristics : infinitely Smart,
Bloodthirsty & Greedy.
Starting with pirate 5 they can make a proposal on how to split
their treasure . This proposal can either be accepted or else
the pirate will be thrown overboard. A proposal is accepted IF &
ONLY IF a majority of the pirates agree on it. What proposal
should the pirate 5 make ?
(Please note that throwing overboard would materialise if & only if
there is a majority decision. A person would support a proposal only
if he thinks :
a) this will get him his biggest gain.
b) there is no better way out.
A pirate is infinitely:
* smart => he will consider all cases possible.
* bloodthirsty => he will kill other pirates if possible.
* greedy => he won't agree to a seemingly O.K. type negotiated
proposal if he thinks that he has a better chance
elsewhere. ( i.e. on some other case of proposal he
thinks will come along...). He will concede to a
proposal only if that is his biggest gain possible
under the cicumstances...)
One thing that arises from the order of seniority mentioned is
that, given two people , the one with the higher rank can kill the
other if he wants. So pirate 2 will never want a case where only he &
pirate 1 remain. So he won't want to throw pirate 3 overboard, for ,
then 1 can kill 2 & get all. So if in a condition where 4 & 5 have
already been thrown overboard after their proposals have been
rejected, if 3 proposes to give one coin to 2 & keep the remaining
999 to himself, 2 doesn't have a choice but to agree. 1 will
definitely oppose this, for if 3 is thrown overboard , he can kill 2
& get all the coins.
But 2 would like to get more coins than just one & so he would want
to keep 4 on board for, it might increase his chances of getting more
from the proposal that 4 makes. 1 & 3 would definitely want to throw
4 overboard for, that maximises their chances of getting more
coins.... Like wise, reason & get down to 5.....)
