"How many times a day does a clock`s hands overlap?"
Very good question... I think I`ll solve it when I get bored in math class.

davymid:

I deleted my post because I realized there were answers at the end, but what I said was indeed correct. I set aside two of the balls, weighed six of them (three on each side), and continued from there.

i met a dude who worked at google and hetold me about a easter egg he put in google earth

first find the google place in boulder colorado
then put the buildings in to 3-d mode
third, look on the roof you`ll see people standing on top of the building

and now you know, and knowing is half the battle!

5: Because the manholes are round
6: Run down hill
8: Most people don`t want to eat live cows
9: He didn`t have insurance
12: Aaaagh, trick question, no one has 8 balls that I know of.
14: "Kid, I really don`t know. I believe it`s magic. Just google it."
15: HA caught you, it said empty, it has no blades.

almighybob1 > I don`t see any reason for your retorts. The question just says "clock", and there are many different ways a clock`s 2 or 3 hands could function as to yield different results.

1) all 3 hands move smoothly,
2) second hand moves in 1 second increments, minute and hour move smoothly,
3) second hand moves smoothly and minute hand moves in increments
4) second and minute hands both move in increments,
5) minute hand and hour hand move smoothly,
6) minute hand moves in increments and hour hand moves smoothly.

*herm* so you`re wrong.

There is no way to survive the blender unless you make outrageous assumptions like your superman or something.

[quote] Unless we`re using the equation that as mass decreases by cubes, strength decreases by the square. [/quote]

Who would use that equation? It makes no sense at all.

My answer to the question was that you`d die on impact with the bottom of the blender, as the question said you were `dropped in`.

Anyway I found a lot of those were interesting. A lot of them were just plain stupid, or perhaps just badly worded.

Bear in mind crakr, the position is for a programmer I believe in that particular question.

As I said, the point is rarely the answer. the point is how you arrived at the answer. In some cases the technical methodology would work, even if you screwed up.

In some cases "One for every 40 pianos" came with a an explanation of how it could be solved. The exact answer was unnecessary.

Got these answered reasonably well. Imho.
Most of these are questions to see if the interviewee has an analytical mind. Unless you are a computer programmer though, The answer to DEADBEEF would elude you because it`s so specific and trivial.

Some were slightly clever, some were lame.

In a technical interview for a position as a scientist with a major multinational oil company, one of my questions was "You`re presented with a beaker containing a liquid. How would you go about determining the temperature of that liquid?"

Thing was, no matter what answer you gave (most obvious example, stick a thermometer in it), they came back with "OK, tell me another way.". I think I came up with 5 or 6 different methods, then got stumped at the sixth "OK, tell me another way".

I found out afterwards that there was no correct answer or finite number of solutions. No matter how many different methods you gave, they`d always ask for another, just to see how far you could push it.

I also call bullpoo on the piano tuners one. Answering "one for every 40 pianos" doesn`t answer the question. Then how many pianos are there?

Unless we`re using the equation that as mass decreases by cubes, strength decreases by the square.

So lets say my height is reduced to 2mm. My mass is reduced by 670 million, my strength is only reduced by 750 thousand. So as an ant-man, I could now jump about 900 times my own height.

At which point I may be able to leap directly out of the blender and out of sight like a flea, and use bounds to get where I wanted to go at reasonable speed.

Additionally, whoever put me in there wouldn`t be able to find me, as I`d have a +16 modifier to my hide skill due to size. (DnD joke).

I call bullpoo on the Seattle answer. They didn`t ask how much per window. They asked how much in TOTAL for ALL the windows. The answer they give is a "non-answer" and just evades the question.

So 12/15.

I knew 24 was wrong for the clocks. I just didn`t quite know how it worked without using tools I didn`t have. (I assume no calculator or paper).

Eggs I screwed up on completely.

If I was as high as a flat nickel, 1) My mass is insignificant in proportion to the blades. I couldn`t do anything. 2) I could hide then starve to death I suppose, or forever live off the scraps people blend in the blender, or until they wash it. 3) If they wash it where would I go? 4) If I escape, I would be more afraid of spiders, ants, roosterroaches, and a many day walk/climb to traverse 10m of counter space. (I dunno how thick a nickel is, but it should roughly multiply all distances by about 1000 by my estimate (to make it simple). Want to walk from one end of the desk to the other? 1.5Km. Want to walk to your car? Say 500Km.

Want to climb a flight of stairs? Worse than climbing Everest.

I`d welcome sweet death first.

If you think you got them all right, you`re wrong. Most of these test your analytical skills, there aren`t always right answers, just "good answers".

I got most of the math ones and logic puzzles right though.

Schoolbus I guessed same as the guy but in metric.
For Seattle, I had no idea.

I know it was 50% boys/girls.
I answered like they did for Piano tuners.
Manhole, easy.
Due to not having a map, my evacuation plan involved the greater USA`s actions, not the city`s.
I guessed 24 for the clock.
I knew DEADBEEF. (Programmer here).
I guessed Monopoly. (Heard it before).
I said "Call me back ASAP". Their answer is wrong, assuming Eve is as smart as him.
Pirates. (Old).
Basketballs. (Got it).
Eggs. (I misunderstood the question).
Explain Database to 8 year old. (This sounds like my job, easy).
Blender: If I`m as high as a flat nickel, let myself die. Otherwise try to dislodge the blades.

How many golf balls can fit in a school bus?
One less than can`t fit in a school bus.

How much should you charge to wash all the windows in Seattle?
Five quid a window

Design an evacuation plan for San Francisco
Why, what are you planning to do?

How many times a day does a clock’s hands overlap?
Clock don`t have hands, you`re thinking of Orangutans.

A man pushed his car to a hotel and lost his fortune. What happened?
Probably the plugs, although you should really replace the distributor as well just to be on the safe side.

aren`t man-whole covers round so they can`t possible fall in?

Twist: probably most famous clock in the world:

2 hands.

And in plenty of 3-handed analogue clocks, the minute hand jumps along from minute to minute. So my answer 22 still holds for those. You ignored this.

You`re wrong. Give up.

Why are some so easy, when the rest are so hard? Like #3, the ratio of boys and girls is 50%. And then #5, round manhole covers are the only shape that can`t fall into the hole. But then the question between them is, how many piano tuners are there in the world, how the drat would anyone know that?

Those are the answers that the lazy reporter looked up from Wiki! Clock = Hour Hand, Minute Hand, and the Second Hand. If you ASSume, there is no second hand, yes 22 times. However, as stated the only answer can be 2 times a day since most analog clocks have 3 hands.

Bob, the question is straight forward. "How many times a day does a clock’s hands overlap?" There is no ASSuming here, the correct answer is 2.

#3: Infinitely low. Each family will have at most 1 boy, but could have infinitely many girls before that one boy.

You forget you cant have infinitely many girls because the normal ratio of girls/boys is 50/50, in the case of a statistic anomaly as you mention, you would have the same on the boys side, many families first baby being a boy.

And also, your solution assumes that the minute hand moves smoothly, whereas plenty of them jump every 60 seconds. If it were a jumping one, then my answer of 22 would still hold for a 3-handed clock.

Not all clocks have 3 hands Twist13. Plenty don`t bother with the second hand.

Ah there`s answers. Solution to 3 assumes p(boy) = p(girl) = 0.5, which I suppose is fair, but isn`t explicitly stated in the question.

I got the time one right though.
