No slight intended, but methinks that maybe you're missing the point of these cute, stupid little brain teaser questions. It's certainly one thing to sit down and slam out something that you either know how to create or can come up with a way to create it relatively easily. It is another thing entirely to solve or approximate a solution to a fundamentally difficult problem and then implement it.
To put it in vulgar terms, Google likely doesn't need people to just get shit done, they need creative solutions to problems that don't have a straight forward answer. Do you honestly think figuring out how to retrieve highly relevant web pages from the whole net based on one or two silly little keywords, in fractions of a second no less, is something you just sit down and program? Do you even think it's something you can beat the current top players at by simply engineering it with current methods? No, it's far more akin to those little problems you hate so much. Sure, there's naive solutions that give a lackluster result, but to do it well it's all a game of tradeoffs, new and novel approaches, application of known approaches or extensions of known approaches in the right instances, a dash of brute force, and who knows what else. If it was straight forward and something just solved by getting shit done then Google and its staff of many PhDs would likely be vanishing due to the costs of keeping all those PhDs around opposed to another company running slimmer and just doing it. Instead they're number one in the search engine world because of their pioneering efforts.
The people who enjoy and excel at those questions, seemingly silly on the surface but generally with deeper implications, are the type that are typically good at doing the sort of research that needs to be done to solve the tricky steps.
Again, none of this is meant as a slight and there really is need for people who are good at architecting and implementing solutions with good work ethics. Many applications are at a point where the technical challenges lie in integration of known solutions and those certainly still need good, hard working architects. On the other hand there's still a definate need for people who like toying with silly questions because that generally translates into enjoying playing with the nuances of more research oriented stuff, simply because they're so often similar. Frankly, if you dislike those stupid little problems then you may well dislike the research experience of bashing your head into brick wall after brick wall trying to come up with a novel solution to a problem which has no real feasible solutions at the moment.

At the risk of sounding arrogant (and, there's no way I'd post this if I weren't doing so anonymously), I was a very qualified candidate. I solved all their puzzles and made an incredibly positive impression on everyone there I visited. Simiarly, Google made a very positive impression on me. It's been my dream to work for them for many years and I finally had the opportunity!
Then, things sort of turned a little bit worse. I was also being courted by a Very Large Software Company. VLSC also made me an offer. It was better, but the money wasn't the issue. Every few days, someone from VLSC would call me to tell me how important it was that I go to work for them. How excited they were about me and extolling the virtues of VLSC.
First my future boss called. His boss called. HIS boss called. And *that* guy's boss called! At this point it was someone very high up in the company. All of them had the same message: we really want you to come here. They started sending little gifts to my house.
Meanwhile, I heard nothing from Google. Their recruiter called me occasionally but never replied to my emails or indicated having read them on phone calls. I asked if it would be possible to speak to anyone else in Google who I might speak with about the type of work I'd be doing or the people I'd be working with. No one ever contacted me. Now, they were getting ready for their IPO so I suppose they had better things to think about, but the overwhelming impression I got was "Your loss if you don't work here. Whatever, come if you want." Meanwhile, VLSC made it clear it would be *their* loss if I didn't work there and that they'd do everything they could to make it the best place ever to work.
It was incredibly painful to have to give up my dream of working for Google. But ultimately, VLSC convinced me that they were more excited about the work I could do and that I'd have a better opportunity there to do it.
I really wanted to want Google. They made it very hard.

Intelligence measures two abilities: learning and reasoning. Being smart is the application of intelligence.
We all know the guy who's ultra-bright at science or math, but bloody useless in the "real world" or (gasp) interpersonal relationships.
People's motivations differ. That person who is ultra-bright may not see applying that logic as something to persue. The benefit of diversity is this: there will always be someone who can take that logic and apply it to something to make it useful to other people who don't care how it works.
What most people see as the goal of life is getting laid and having children (most of the time subconsciously) thus propogating the species. The basic law of nature (and man) is to survive by any means necessary. Most people make their attempt at immortality via offspring, some through presence (actors), others through published works/name recognition. There are also a number of people who create a fictitious being and place where they will live out eternity in bliss (religion).
Since it is illegal to test people's intelligence in the U.S. for a job, google is going to where the smart people are. I see nothing wrong with that. Reading a person on paper (that they wrote) is not a very accurate means for judging a person's intellect or skills. Testing their abilities just to get to the application is a smart thing to do.
None of this is about elitism. Some people do feel superior to others and are truly elitists, but it is generally the other people who feel inferior and have to tear the "elite" down by any means available.

Now lets add a resistor:
1/Rt = 1/R1 + 1/R2 + 1/R3 + 1/R4
1/4
Rt =
see how it gets smaller every time you add one?
SO if you continually add one, its continually gets smaller.
So the correct answer is:
1/Rt = 1/R1 + 1/R2 + 1/R3
