#402 - Hard Adobe Interview Puzzle Question
There are a hundred statements.
First person says: At least one of the statements is false.
Second person says: At least two of the statements is false.
Third person says: At least three of the statements are false.
Fourth person says: At least four of the statements are false.
..
..
..
Hundredth person says: At least a hundred of the statements are false.
Analyzing it, how many statements do you think are false and how many are right?
The hundredth statement is surely false as it says that at least a hundred of the statements are false.
But in a situation if that is correct, then hundred statements cannot be right.
This implies that the hundredth statement is wrong and that the first statement is true.
Similarly ninety nine statements can’t be true as if they were correct, then two statements would become correct i.e. the first and the ninety ninth.
But the ninety ninth statement says that at least ninety nine are wrong.
This implies that the ninety ninth statement is false and that second is correct.
If we go on calculating in the similar fashion, we will come to the conclusion that:
The first fifty statements are right and the remaining fifty statements are false.
#403 - Critical Thinking Puzzle
An innocent person is accused of a murder in a village. The head of the village knows that the man is innocent but he also knows that the truth may be uncovered one day that his own son is the murderer. Just to hinder the attention of people, he offers a chance to the man. In a jar, he places two chits of paper – one reads innocent and the other reads guilty. Among all the other villagers, he asks the accused person to pick up a chit. He says that their almighty god is watching them and the person will meet his fate truthfully with the chit.
Of course, the village head is cheating. He has put both chits with Guilty written on them. The accused person somehow suspects the same. But no one will believe him if he tries to expose the head. Also, he knows no one will look at the other chit once his fate is decided by his selected chit.
What should he do to prove that he is innocent?
When asked to draw a chit, the person will pick any and then without looking at it, he will swallow the chit. In this manner, to decide his fate, they will have to look at the other chit which reads Guilty. Thus people will understand that the chit which he ate had innocent written over it.

#408 - Death Match Riddle
In the Wild West, you are challenged into a death match by two bounty hunters nicknamed Golden Revolver (GR) and Killer Boots (KB). You accept the challenge. None of you want to waste any of the bullet and so a certain rules are laid down:
1) All of you will shoot in a given order till the last man standing.
2) Each of you shoots only once upon his turn.
3) If any one of you is injured, the other two will finish him off with iron rod.
4) The worst shooter of all (which is you) shoots first and the best one shoots at the last.
Now, how will you plan things if you know that you hit every third shot of yours, KB hits every second shot and GR hits every shot ?
The best thing you can do is shooting your first shot in the air.
Suppose if you shoot KB and hit him by luck, you are certainly dead as GR never misses.
If you shoot on GR first and hits him luckily, there is a fifty percent probability that you will die before your next chance.
But if you shoot in the air, KB will definitely shoot on GR as he knows that he is a better shooter. If he misses somehow, then, he is dead and if he hits then, GR is dead.
Now it’s your turn to shoot and you stand a 1/3 chance that you will hit.
This is the best situation you can have. Doing anything else will bring you under worse situation for sure.

#410 - Classical Probability Puzzle
If we roll two dices (six sided normal dice) together.
what is the probability that the first one comes up with a 2 and the second one comes up with a 5?
The probability will be 1/36.
For the first dice, there can be six possibilities. Similarly, for the second dice as well, there can be six possibilities.
Thus the total possibilities is 6 * 6 = 36.
The outcome we need is that the first comes up with a 2 and the second comes up with a 5. That is possible only in one possibility.
Therefore the required probability is 1/36.
