Re: *DI Marathon for CAT 2007* - 04-09-2007, 07:36 PM

Hi . This is my first attempt at creating a DI set - sorry if you find it a bit confusing ..

A group of 12 people are bored to death in a classroom. They decide to spend time playing a game of murderer. They sit in a circle . They pick up chits to decide their roles : 1 person will be the Murderer , one person will be the Police and the rest are 'People'. The people playing the game keep their roles as secret and do not disclose it to anyone. The objective of the game if for the murderer to kill people by winking at them(Nobody except the Murderer will wink in the game). Once a person is killed in this fashion , he announces himself dead and does not take further part in the game. If the Murderer kills 5 people , the game is over and he wins. The police has to constantly watch the people in the circle to find out who the Murderer is. He can make 3 guesses . If he correctly identifies the murderer , the police wins. In the case of an incorrect guess , he kills the person in an 'Encounter' leading to the death of the person guessed and that person counts to the 5 person Murderer win goal.

1) What is the least percentage of total people playing the Murderer could have actually killed and won the game?
a)16.66%
b)33.33%
c)50%
d)75%
e)100%

2) Which of the following is a possible percentage (out of Total People Playing) distribution of the people killed by Murderer and People mistakenly killed in encounters leading to a Murderer win?
a)33.33% , 16.66%
b) 25% , 16.66%
c)33.33% , 33.33%
d)None of these
e)Cannot Be Determined

Now a new role called Suicide Bomber is created. If this person is killed by the Murderer or incorrectly guessed as murderer by the police , he will explode and kill the 2 people adjacent to him will also die. (This will count as a total of 3 kills towards kill goal unless one or both of the adjacent people was already dead).If one of them is the police , the Murderer wins. If one of them is the Murderer , the police wins. In case both die , the game ends in a draw.

3)Which of the following will surely lead to a draw?
i)3 Continuous People in the circle get roles which are not Persons.
ii)The Murderer winks at the suicide Bomber.
iii)The Police kills the Suicide Bomber by mistake in an 'Encounter'

a) i and ii
b) i and iii
c) Both a and b
d) None of the above

Re: *DI Marathon for CAT 2007* - 04-09-2007, 09:39 PM

1) What is the least percentage of total people playing the Murderer could have actually killed and won the game?

To win , there has to be 5 kills. 3 of these can be wrong guesses on the part of the Police. That leaves at least 2 kills to be done by the murderer.
2/12X100 =
a)16.66%

2) Which of the following is a possible percentage (out of Total People Playing) distribution of the people killed by Murderer and People mistakenly killed in encounters leading to a Murderer win?
Again , the number should add up to 5.
Only b) 25% (3 People) , 16.66% (2 People) adds up to 5

3)Which of the following will surely lead to a draw?
i)3 Continuous People in the circle get roles which are not Persons.
ii)The Murderer winks at the suicide Bomber.
iii)The Police kills the Suicide Bomber by mistake in an 'Encounter'

a) i and ii
b) i and iii
c) Both a and b
d) None of the above


It is possible to have a arrangement of ...-Suicide Bomber -Police- Murderer-...
So none of the cases would have led to a draw

Hi siddooba,
A little confusion in ur soln for question 1.
If police kills three people by mistake,
the murderer wins there itself, why would he kill further.
so the answer should be 0%(killed by murderer) and not 16.66%.
please explain me as i am confused.
Regards,
Koush

I think he has a point here. If the police has made 3 attempts all his chances are expired
and he definitely fails. But the murderer doesnt won not yet. For murderer to win the count =5 , so he should kill 2 more persons.So the answer is again 16.66% only.
