Heres a great brain teaser for you guys!
Those of you who have seen this one before please don,t ruin it for the others.

Read the sentence that follows and then count the number of the letter F,s you see in the sentence after you read it. And post the number you come up with.

Here is the sentence you must read and then count all of letter F ,s that you see.

Finished files are the result of years of scientific study combined with the experience of years.......


How many of letter F did you see???:confused:
You,ll be amazed with the result, I was!:cool:

You should come up with a total of 6 F,s.
Yes they are all there! believe it or not.
 
Your brain sees the of,s as a v in your head, I only came up with 3 the first time around as almost every one does.
 
Sorry but I came up with six as I sit in a hotel room from cold northeast New York.
 
Dude- I got 12 :p:p

I actually never got to 6- got three at first then 4 and then 5 and then, well, looked for the answer.
 
very good, I only came up with three before giving up and looking at answer
 
I got our at irst, then ive when I recounted and inally got to get all fix:rolleyes::confused:
 
That's one of my favourite brain teasers and here's another that's rather difficult if you haven't heard it before:

A traveller comes to a fork in the road and does not know how to get to his destination. Two men are at the fork in the road. One of them always tells the truth, and the other one always lies.

The traveller may ask one of the men one question to find his way.

What question does the traveller ask?
 
Ask him what day it is, what time it is or what country he is in.
 
Remember that you are only allowed one question, which will have to be about which road to take so you can't waste the one question asking something you already know to check if he is the liar or honest person.
 
Okay there's two men at the fork and since you are at the fork you are one of them. You already know you are a lying sack of fecal matter so you ask him how to get where you' re going.

Hi Oz,

I believe the answer to you riddle must be something like the following:

If I were to ask you if the road to the left leads to my destination, would you say yes?

My logic:

The liar, upon realizing that if he were only asked, "Does the road to the left lead to my destination," would have to provide an answer that disagrees with the truthteller. However, since the question is a hypthetical one, he must lie about how he would answer the question were it not phrased in such a manner. Let me illustrate how this would work for the liar:

Assume the correct answer to the question, "Does the road to the left lead to my destination" is Yes. The liar would have to say no. However since the question is hypothetical (If I were to ask you...), in order to lie, the liar would have to answer yes, thereby agreeing with the truth teller. Since the two answers would agree, the traveler would know the answer he received would be correct regardless of which person answered. Have I explained that in a sensible manner? Let me illustrate my response in one other way.

If the question posed is:

Does the road to the left lead to my destination, the answers would be as follows:

Truthteller: Yes (or no depending on the truth)
Liar: No (or yes depending on the truth)

In the above illustration, the answers disagree.

By asking "If I were to ask you does the road to the left lead to my destination, would you say yes", the answers would be as follows:

Truthteller: Yes (or no depending on the truth)
Liar: Yes (or no, because he must lie regarding how he would answer if the question were phrased without the "What if" possibility)

By phrasing the question as a hypothetical one, the answer provided by the liar must agree with the one provided by the truthteller.

Whew! That was work! Let me know if the answer is the one you seek.

Warmest personal regards,

Pat :)

It wouldn't be much of a brain teaser if the scenario was that obvious.

Pat, you are so close, and if you were allowed to ask two questions your answer would be correct. And of course if two questions were allowed, then the idea of eborris would have worked.

However as I said before, the traveller is only allowed to ask ONE question. Therefore the traveller can only ask the one quesition to one of the other two men.

Pat, I didn't get the correct answer to this teaser, but I think you can if you have some more coffee and think of that one hypothetical question to ask.
 
I would ask which road should I not use. If I ask the truthteller he would point me to the right one. If I asked the liar he would point me to the right one to because its a lie to my question.

This sounds like the right answer to me, good call.

Jeff
 
But the point is you don't know which of the men is the truth teller and which is the liar, so your question has to be one which would generate the right answer from both men.

I think the answer is to ask "if I asked the other guy which way leads to my destination, what would he say?"

If you ask the liar, he will tell you the wrong way, because he always lies.

If you ask the truthful guy, he will tell you the wrong way because the other guy always lies.

Then just go the opposite way.

Am I right, Oz?
