Vivek, mujhe tumse yeh umeed nahi thi

You are the one who cracks every riddle with so much ease that I am forever trying to wish myself into nothingness....

What's your (as always, correct) take?

Arrey maine aisa kya kiya ki aap na-umeed ho gaye?

I just wanted to say that your approach sounds perfect to me . Ab Shivani aake confirm kar de. Since this is a lateral thinking problem, it can have multiple answers.

And someone once had a signature here on HF the gist of which was that modesty is not a good thing (don't remember exact words). So Jaadugarji, start accepting your capabilities .

Cheers,

Suhas.. stop fishing for compliments.

Vivek, I just present the problems here in hope that one of you would be able to solve them, and in the process I will learn. Please do not wait for my confirmation, and .. carry on..

Next one , since no one posted another..

"Travelling to a city, an old man lost his way. He came to a fork in the road and did not know which road to take. Standing at the fork were two men. Next to the men was a sign, which you may assume is correct, which stated that one of the two men always told the truth and one of the men always told lies (but it was not known which was which). The sign went on to say that travellers could only ask one of the men one question.
What question could the old man pose that would give him the information he needs to choose the correct route? "

[Mandrake]

Shivani-ji, you always get me wrong

jaande do....

is the traveller allowed to ask 1 question to each man, or totally 1 question?

[shivani]

Shivani-ji,

You dont ever talk to me again.
And the traveller has to ask one Q .

Shivani, appreciate your efforts to post these questions. All of them have been a good learning experience for us.

And here is a possible solution to your problem.

Assuming I am the old man (which I am not ), I will ask following question to one of the two men. Assume that the two roads are named X and Y

I will ask following question to one of the person.

What will be the answer of the man standing next to you if I ask him "whether Y is the correct path for me?"

{
A = Men who tells the truth
B = Men who never tells the truth
}

1. Now if the person I asked the question is A, and if Y is correct path, he will say that other person will say "No" (because other person is B who is a liar and would have answered No because Y indeed is correct path, if I had asked him directly).

2. Now if the person I asked the question is B, and if Y is the correct path, he will say that other person will say "No" (because other person is A who always speaks the truth and he would have answered Yes if I had asked A directly).

3. If Y is incorrect, A will say that other person will say "yes".

4. If Y is incorrect, B will say that other person will say "yes".

So in both the cases, I will do exactly opposite to what the person answers me. So in cases 1 and 2 I will take Y (since the answer was NO) and in cases 3 and 4, I will take X (since answer was yes for Y)

Hope I have covered all the cases

An eternity later, the data trickles in - the lines that sum up the situation:

Hats off to the AMAZING Vivek!!!

Ok a question from my side now. Not very tough...

There are 6 ladies and each of them has recently heard a hot new gossip (I mean different piece of gossip). By nature, they want to share their information with each of the other 5 ladies. What is the minimum number of phone calls they need to make such that each one know all 6 gossip stories?

Forgot to add, when lady A calls lady B, both of them tell each other their information. So at the end of the call A knows her gossip as well as B's gossip.
