A mathematical question

A man is initially standing at a certain point A. He starts walking 100 metres towards the east, then 50 metres towards the north, then 25 metres towards the west, then 12.5 metres towards the south, then 6.25 metres towards the east, then 3.125 metres (half of the previous distance) towards the north, and so on. Finally, He reaches a final point B after repeatedly walking in this fashion. What is the distance between points A and B?

Perfect in limits...hmmmm?

I think you have attained mastery in limits. So try out the following two problems..Similar but quite different......and please don't hesitate to comment...

So here they are:

I think its obvious that the answer is not obvious!

Tricky number

Find out a 10 digit number in which 1st number denotes number of 0's in it , 2nd number denotes number of 1's in it , so on and 10th number denotes number of 9's in the number. find the number

The number is unique

{Bit of logical + mechanical}

And i was right.....

I know i am a little late, but i had predicted Russia's win over holland, and i wud have told u ppl abt this had my net usage not overshooten...Well i guess only my brother stands testimony to that.
Well after the portugeese defeat , i predicted that Russia vs Germany will be the final and ocourse Russia will win.Well i wnt tell the exact reason, bt its NOT any kind of gut feeling.

The Brilliant Mananger

There is a hotel which has infinite rooms. One day, infinite guests arrive and fill those rooms (obviously some rooms would be empty!). Suddenly, at midnight, a VIP arrives and demands a room for himself immediately. The manager of the hotel is not at all worried and arranges for the room in one minute. How is it possible to find one empty room out of infinite rooms in just one minute!?
Level- Easy
P.S. - This puzzle was given to us by our maths teacher while doing the chapter relations and functions!

The CraZy Receptionist

One day, a man walks into a restaurant and asks for water. To his surprise the receptionist takes out a gun and points it to his forehead. Astonishingly, the man says, "Thank you so much!" and leaves the restaurant! Can you explain the situation?
Level - You decide!
P.S.- I heard this puzzle on the radio!

Congratulations

Well , I just saw the bottom of the blog where it is mentioned that the site has been online since 10th May 2007
So congratulations to all of us for keeping this radical blog alive for more than a year. This blog is really a proud achievement of all of us.
What do you think?

Bloxorz

The link on the right is of a game "Bloxorz". Its a really nice and puzzling game. See if you can cross all its levels.

A paradox

I dunno if you get intrigued by this paradox, but i was and did sone thiking over it(too obvious, after all thiking is what i love to do). However, surprisingly i also came up with some conclusion. i will share that but you opinions first.

Achilles and the Tortoise

Achilles and the tortoise is similar. Suppose that the swift Achilles is having a race with a tortoise. Since the tortoise is much slower, she gets a head start. When the tortoise has reached a given point a, Achilles starts. But by the time Achilles reaches a, the tortoise has already moved beyond point a, to point b. And by the time Achilles reaches b the tortoise has already moved a little bit farther along, to point c. Since this process goes on indefinitely, Achilles can never catch up with the tortoise.
