How many of each animal were there?

10 Cockroaches
35 Crows
5 Mice

x = Crows
y = Mice
z = Roaches

x + y + z = 50
2x + 4y + 6z = 150
z = 2y
x + y + 2y = 50, x + 3y = 50

Ahhh, screw it... You don't want to see this. :p

Question 321 - RESOLVED

This one's for you then.

You are in a room with 2 doors leading out.

Behind 1 door is a coffer overflowing with jewels and gold, along with an exit. Behind the other door is an enormous, hungry lion that will pounce on anyone opening the door.

You do not know which door leads to the treasure and exit, and which door leads to the lion.

In the room you are in are 2 individuals. The first is a knight, who always tells the truth, and a knave, who always lies. Both of these individuals know what is behind each door.

You do not know which individual is the knight, or which one is the knave. You may ask one of the individuals exactly 1 question.

What should you ask in order to be certain that you will open the door with the coffer behind it, instead of the hungry lion?

__________
You ask one of the individuals what the other one would say if you asked him which door is holding back the hungry lion and then open this door.

Ah, a classic. Ask either one, which would the other person say is the door to the coffer and take the other one. The knave, knowing the knight would give the correct answer, will direct you to the wrong door. The knight, knowing the knave would direct you to the wrong door, would answer truthfully and direct you to the wrong door as well.

Ask one of them if the other one would tell you that the first door is the way out.

Ask any one of them to open the door that has the exit...

if it was the knave, then he'll open the door to the lion, he'll get eatten, and you would know the other door was the correct on...if it was the knight, then he would open that correct door
