    That one is a classic.

    Here is one from me:

    John and Paul live in a village. One day John decides to walk to the nearby town, but Paul wants to stay back.

    So, John starts walking towards the town at 10 KMPH. After 1 hour, Paul feels lonely and decides to also go. So, he starts walking towards the town at 15 KMPH. At the sametime, Paul's dog starts running ahead of him at 20 KMPH.

    The moment the dog catches up with John, it turns around and starts running back to Paul, still at 20 KMPH. The dog continues the running between the two men till Paul catches up with John.

    What is the total distance travelled by the Dog?

    Reality is merely an illusion, albeit a very persistent one.

    Usually I'm averse to using my grey cells in such mathematical calculations. Plain lazy! Incorrigibly so! The Einstein puzzle too I was not inclined to try at first and watched happily as our children finished solving it one by one. But when my younger sister, a doctor, too found time to solve it I had no option than to prove my mettle! I never budge out of my sloth unless properly challenged!

    Hope al the stalwart hubbers who made this thread abuzz with brilliant activity come back!

    Going back to high school days !

    Assume x to be the time it takes Paul to catch up with John.

    Paul walks 15x miles to catch up with John and during that time John walks 10+10x miles.

    10+10x = 15x or x= 2 hours

    In two hours the dog runs 40 KM

    Of course, high school students would have complained that the question paper was very difficult !

    In one hours time the distance between John and Paul is 10 Kms. John approaches with a relative speed of 5 Kmph so it would take him 2 hours to reach John.

    In 2 hours time, assuming that the dog wouldn't have to decelerate while turning back and changing directions, it would have covered 20 kmph x 2 hours = 40 Kms.

    Of couse Rajraj solved it elegantly already but I did not use the dreaded alphabet 'x' so I thought I'wd post it

    Here is one easy questioon...

    A craftsman has 5 short pieces of chains as shown below. Each piece contains 3 rings. He has to connect them all into one long chain.

    OOO OOO OOO OOO OOO

    Every operation that he performs on the rings is going to cost him lots of time (Note that unlinking a ring is one operation and linking it to another ring is another operation). What is the minimum number of operations needed to link the chain together and how?

    For sake of explaining, you can number the rings 1 to 15 and elaborate.

    Rajraj, seems like your question cannot be answered without Google or Wiki's help... Any clues please? Or else you will get all sorts of imaginative answers :P
