theiswe:You can ask either of the twins the following question: "Which way would the other twin tell me to go?" and then you go the opposite direction!
Lets say Left is the correct way, and right is the wrong way.
If you ask the truthful twin (A) which way the other twin (B) would tell you to go, twin A will tell you that twin B would say "Right".
If you ask the lying twin (B) which way the other twin (B) would tell you to go, twin B will tell you that twin A would say "Right".
Therefore you should go the opposite way of what either of the twin replies to your question
reinout-g:Little logic's puzzle for whoever is interested,
You are on a quest from Proqzanthar to Krighontyr but find a T-crossing and don't know which way to go.
At the T-crossing there are two twin brothers of which one is always true and the other is always false, but you don't know which one is which.
You can ask only 1 question to either of the two brothers.
Which question do you need to ask to know whether to go left or right?

I am not sure that I understand the question.
If I can ask 1 brother 1 question and then ask the other brother a different question then I know how to do it.
Is this what you meant?

C1, A1, C2, A2, C3, A3 to get across the river
first C1 and A1 paddle across the river C1 stays
A1, C2, A2, C3, A3
Now C2 and A2 paddle across the river C1 and C2 stay
A1, A2, C3, A3
Now C3 and A3 paddle across the river C1, C2 and C3 stay
A1, A2, A3

C3 and A3 paddle across and then they are all there.
Is that okay or is there a better answer?
NO WE HAVE TO SCRAP THIS ONE IT DOESN'T FOLLOW THE RULES - SORRY.

Same as before. We have three coaches C1, C2, and C3
and we have 3 athletes A1, A2, A3
So A1, A2, A3, C1, C2, C3 all have to get accross the river
A1, and C1 paddle across and A1 stays on the other side (C1 returns)
So A2, A3, C1, C2, C3 all have to get accross the river
C1, and C2 paddle across and A1 AND C1 stays on the other side (C2 returns)
So A2, A3, C2, C3 all have to get accross the river
C2, and C3 paddle across and C1, C2 and C3 stays on the other side (A1 returns)
So A1, A2, A3, all have to get accross the river
A1, and A2 paddle across and A1, C1, C2 and C3 stays on the other side (A2 returns)
So A2, A3, all have to get accross the river
A2, and A3 paddle across and everyone is on the other side

Three rivalling coaches (Pierre(A1), Pieter(B1) and Peter(C1)) and their three athletes (Édouard(A2), Eduard(B2) and Edward(C2)) want to cross a river.)
There is only one boat which can carry two persons.
The coaches do not want other coaches to be with their athlete without they themselves beeing present at any moment..
How can they cross the river?
A1 A2 cross the river, A1 came back.
A1 B1 cross the river, B1 came back.
B1 B2 cross the river, B1 came back.
B1 C1 cross the river, C1 came back.
C1 C2 cross the river, the end.
I'm sorry to say your answer is incorrect,
in step two, B1 is in the presence of coach A2
Answer to the quiz about (Pierre, Pieter and Peter)
and their three athletes (Édouard, Eduard and
Edward)
First édouard and eduard enter the boat to the other side, eduard drops off and édouard paddles back and picks up pierre. Édouard drops at the other side and pierre paddles back and picks up pieter. They both drop off at the other side. Édouard paddles back again and picks up edward. Édouard drops off at the other side and edward paddles back and picks up peter. They both drop off at the other side.
In essence no athelete is left in th presence of another coach without his coach being present.
Pierre is shortly in the presence of Eduard when he drops of éduoard. Therefore, your answer is incorrect
the only question you need to ask is if they like one direction whoever says yes is the brother that tells the truth whoever says no is a liar if neither then lick their hair :)
You ask one brother what the other one would say, and then go the opposite, because if they are lying you go the opposite of what they tell you and if they are telling the truth about what the other would say then you would still go the other way. BOOM
You ask one brother what the other brother will tell you is the correct way, then go the opposite way.
If you ask the truthful brother, he will respond with what the lying brother says, which would be the wrong way.
If you ask the lying brother he will lie about which path the truthful brother would say- so either way you go the opposite of what they say.
Ask a Random child,if he say this way, say “ are you sure "
“promise ok?”
if you lie,your nose will be long!”
“I'm telling the truth,when you lie your nose will be long"
He might sound scare and that me he is telling the lie!
C=coach A= athelete
C1A1, C2A2 C3A3 start off the same side. A2 crosses with A1. A2 returns but leaves A1. Boat is with the starting side. C1, C2A2, C3A3((RIVER)) A1
A2 crosses with A3, leaves A3, and returns. Boat is on the starting side and A1 and A3 have crossed.
Now the arrangement is C3 C2A2 C1((RIVER)) A1, A3. The boat is with the coaches.
C3 and C1 cross. Now just C2 A2 remains. C2A2 ((RIVER)) C3A3 C1A1. However, the boat is with C1A1's side.
C1A1 returns with the boat, so now it is C2A2 C1A1 ((RIVER)) C3A3. Boat with C1A1's side.
C1 and C2 cross. Now it is A2, A1 ((RIVER)) C3A3, C2, C1. Boat on C1 and C2's side.
A3 crosses. A2,A1,A3((RIVER))C3,C2,C1. Boat is with A3's side.
A2 and A3 cross. Now it is A1((RIVER))C3A3, C2A2, C1. Boat with C1's side.
C1 crosses. Now: A1C1 ((RIVER)) C3A3, C2A2. Boat with A1C1's side. A1C1 Cross, YAHOO!

It is time for a new logic puzzle!!
It took me a while to solve this one, but eventually I found the answer.
There's a street with 5 houses with 5 different colors in a row. Each house has a owner with a different nationality, each owner drinks a certain type of beverage, smokes a certain brand of cigar and has a certain pet. All owners have a different pet, type of cigar or drink. There are 15 hints given:
1. The Brit lives in the red house.
2. The Swede keeps dogs as pets.
3. The Dane drinks tea.
4. The green house is on the immediate left of the white house.
5. The green house's owner drinks coffee.
6. The owner who smokes Pall Mall rears birds.
7. The owner of the yellow house smokes Dunhill.
8. The owner living in the center house drinks milk.
9. The Norwegian lives in the first house.
10. The owner who smokes Blends lives next to the one who keeps cats.
11. The owner who keeps the horse lives next to the one who smokes Dunhill.
12. The owner who smokes Bluemasters drinks beer.
13. The German smokes Prince.
14. The Norwegian lives next to the blue house.
15. The owner who smokes Blends lives next to the one who drinks water.
Find out who owns the fish...

Nationality | Norwegian | Dane | Brit. | German | Swede. |
Drink | Water | Tea | Milk | ???? | Beer |
Cigar | Dunhill | Blends | Pall Mall | Coffee | Bluemaster |

Well done anonymous!
I think something messed up your table a little but your answer is still correct.
Do you have a registered account, so I can see who's the genius behind the answer?
If you don't please do... It takes little time and makes us able to identify you on the forum.

Believe me, I would join but the terms of agreement still don't set right with me. Thankyou for the invite but I have to decline.
Hi Anonymous,
If you are a conscientious objector we can respect that.
If you post a lot why don't you give yourself a unofficial username - you can put it at the end of all your posts and we will slowly learn who you are.
We would really like you to be a proper 'member' of the forum even if it is unofficial.
"If I asked the other one which way not to go, what would he say?" Then you go that way.
you would ask a question to one twin that you knew the correct answer to and if the twin got the right answer that was the one that always told the truth so you ask his brother which way to go and he would tell a lie so if you needed to go right he would say left so you would know to go right.
Or, the brother that always told a lie would answer the first question which means he would get the answer incorrect. so you would know that the other brother always told the truth. so if he told you to go right you would know to go right and if he told you to go left you would know to go left.
I would ask the brothers if the ground is dirt. If a brother says no, then he is lying and I shouldn't go his way.
So confusing. You have good questions, or puzzles. Really good question. May you please give me a hint?
Wait! This game is is a bit like the Chinese card game number 24 except the magic number doesn't change!

The puzzle:
I looked at this for 15 mins before giving up and looking.
Puzzle 1: Point to leftmost card and ask "Is there an ace to right of this card?"
This would only work if the jack isn't the middle.
Other that that, I'm stumped..(only thought on it for 10 minutes)
Puzzle 2: "What would the other god tell me?"-Taken from the twins puzzle
Puzzle 3: "If ja means yes, is Dushanbe in Kirghizia?"
