No, it means

But remember, there are multiple solutions for this puzzle.

According to Wikipedia, (remember, I got this off Wikipedia, so I didn't come up with the idea) the answer there is:

but I like yours better, it's a LOT less complicated. There are multiple solutions, so I'm not saying yours is wrong.

Hmm, that is an interesting way to to determine what "ja" or "da" means. It's not what I was thinking of, but it still works. However, you still need to determine the identities of the cheifs.

I'll give you a hint:

The other day, we did an AWESOME activity in math class. We played around with suction cups!

My math teacher wanted to teach us about air pressure, so he brought in some suction cups and we did some things with them. We all tried to pull them apart, and I pulled so hard I fell out of my chair, really! Then we got to hang off the doorframe with suction cups. I lasted a while, and I only came down because my fingers started to hurt. We also saw some cool tricks: if you put something flat and laminated on top of a glass of water, it sticks and you can hold it upside down without it gushing out.

My teacher also put some toilet paper rolls on a fan and put a baloon on top of the rolls. The air from the fan held it up - it was floating in midair! Then he gave us a straw and a pingpong ball, and we held up the ball by blowing through the straw. It was fun!

Best of all, it turns out that for the rest of the school year we'll be building rockets in math class! YAY! big_smile

Hello, Chilli the Cow here.
Here's a logic puzzle I read about on Wikipedia. It's supposed to be the hardest ever...it's kinda like Knights and Knaves, but with a twist.


You are on a trip to a tropical island. As you find out, the island is inhabited by three tribes. As it turns out, you arrive right when the chiefs of these tribes are all meeting. One chief is wearing a blue headress, one is wearing a green one, and the other is wearing white. One cheif always tells the truth, one always lies, and one can either tell the truth or lie, but you don't know which is which. The chiefs are very busy and only have time to answer one yes-or-no question each, and each question must be directed at one of the chiefs. The chiefs can understand English but they can't speak it, so they answer in their own language. You know that the words "da" and "ja" mean "yes" and "no", but you do not know which word means which. Taking that all into consideration, what questions will you ask to determine which chief is the truth-teller, which lies, and which can do both?

I found this funny list of annoying things to do in an elevator:
These are REALLY tempting!


Announce in a demonic voice: "I must find a more suitable host body."
Ask each passenger getting on if you can push the button for them.
Bet the other passengers you can fit a quarter in your nose.
Blow spit bubbles.
Blow your nose and offer to show the contents of your kleenex to other passengers.
Bring a chair along.
Burp, and then say "mmmm...tasty!"
Carry a blanket and clutch it protectively.
Crack open your briefcase or purse, and while peering inside ask: "Got enough air in there?"
Do Tai Chi exercises.
Draw a little square on the floor with chalk and announce to the other passengers that this is your "personal space."
Frown and mutter "gotta go, gotta go" then sigh and say "oops!"
Give religious tracts to each passenger.
Greet everyone getting on the elevator with a warm handshake and ask them to call you Admiral.
Grimace painfully while smacking your forehead and muttering: "Shut up, dammit, all of you just shut UP!"
Holler "Chutes away!" whenever the elevator descends.
If anyone brushes against you, recoil and holler "Bad touch!"
Lean against the button panel.
Lean over to another passenger and whisper: "Noogie patrol coming!"
Leave a box between the doors.
Listen to the elevator walls with a stethoscope.
Make explosion noises when anyone presses a button.
Make race car noises when anyone gets on or off.
Meow occassionally.
Offer name tags to everyone getting on the elevator. Wear yours upside-down.
On a long ride, sway side to side at the natural frequency of the elevator.
On the highest floor, hold the door open and demand that it stay open until you hear the penny you dropped down the shaft go "plink" at the bottom.
One word: Flatulence!
Play the harmonica.
Pull your gum out of your mouth in long strings.
Say "Ding!" at each floor.
Say "I wonder what all these do" and push the red buttons.
Sell Girl Scout cookies.
Shadow box.
Shave.
Show other passengers a wound and ask if it looks infected.
Sing "Mary had a little lamb" while continually pushing buttons.
Stand silent and motionless in the corner, facing the wall, without getting off.
Stare at another passenger for a while, then announce "You're one of THEM!" and move to the far corner of the elevator.
Stare at your thumb and say "I think it's getting larger."
Stare, grinning, at another passenger for a while, and then announce: "I've got new socks on!"
Start a sing-along.
Take a bite of a sandwich and ask another passenger: "Wanna see wha in muh mouf?"
Walk on with a cooler that says "human head" on the side.
Wear "X-Ray Specs" and leer suggestively at other passengers.
Wear a puppet on your hand and talk to other passengers "through" it.
When arriving at your floor, grunt and strain to yank the doors open, then act embarrassed when they open by themselves.
When at least 8 people have boarded, moan from the back: "Oh, not now, darn motion sickness!"
When the elevator is silent, look around and ask "is that your beeper?"
Whistle the first seven notes of "It's a Small World" incessantly.


If you can come up with any more funny things to do in an elevator, feel free to post them...

Hi, it's me, Chilli the Cow!

I'm a new member to the forums, but I've been around the Maths Is Fun site. I love playing the games during studyhall in school.

I like to do the logic puzzles too! I can tell that I'll have fun here at the Maths Is Fun forum.

By the way....if you're wondering why I'm called Chilli the Cow, I got it from a news article. There's a 6-foot-6 cow in England named Chilli who weighs over a ton! yikes Imagine that! And that's him in my avatar too. You can read about him on this webpage: http://www.dailymail.co.uk/sciencetech/article-565909/Pictured-The-giant-6ft-cow-big-small-elephant.html
