How are you in maths?

9/10, but surely the right answer here is 8am? 18km at 1.5 km/h will take 12 hours? The Gotemba walking trail up Mount Fuji is about 9 kilometres (km) long. Walkers need to return from the 18 km walk by 8pm. Toshi estimates that he can walk up the mountain at 1.5 kilometres per hour on average, and down at twice that speed. These speeds take into account meal breaks and rest times. Using Toshi’s estimated speeds, what is the latest time he can begin his walk so that he can return by 8pm? 10am 11am 12pm 1pm

so you don't own a mobile phone - I haven't seen one, not even a dumb one that doesn't include a calculator - or a PC - Windows comes with one, every version of Linux I've seen also does, I suspect Macs do as well. So I'll go with the poor option as well.

I agree. This was less of a maths tests than a reading comprehension test.

On #7, that's a very astute observation! The obvious solution, and the one most of us used and were scored as correct, is that all three compartments are full. But of the three, only two will be entering; one will be filled with people leaving. Your answer is technically correct in a real world sense, but when has a mathematician concerned himself with reality? :-D On #9, I don't know which you picked, but 26.58 is clearly 0.08 larger than 26.5. It is normal practice to omit trailing zeroes unless a fixed width format is specified.
Will Rogers never met me.
Actually none of the answers were correct, not even mathematically, unless the question had been "how many people could pass the door in 30 minutes on average?" My point is that if people start entering at T0=0 no one is in either compartment, and it will take about the time of half a rotation (~7.5s) before the first pair of persons will emerge on the other side. After that 2 persons will exit the door every 5 seconds (1/3rd of the time of a full rotation). At T1=30minutes, 30*60=1800 seconds have passed, but only 1792.5 seconds have passed since the emergence of the first pair, so only 358 pairs will have time to pass after the first one (taking 358*5s=1790s), for a total of 718 people, not 720! I am well aware that this answer is even less practically useful than 720, but if this is supposed to be a math test, such a subtlety should be considered! A similar, but less complex question would be this: You want to build a fence that is 30m long, and you need to put a fence post every 2m. How many fence posts do you need? This is a typical "one-off" question, where you need to consider the exact starting and stopping conditions to make sure your count is not one off the actual number. It should be well known to programmers too, when it comes to counting loop iterations!

The text was a bit confusing as the "18km" imply the total of both ways, but each half was to be calculated differently. Like pretty much every other question here it was more of a reading comprehension test than maths. :doh:

Got a 10 out of 10. Was pretty simple, but it should have been simple for someone that majored in Mathematics in college.

Lazy..... Too lazy to take a math test willingly to see how good I am at math.

I used to be good in math, and let it be that way... ;P

I was always the weird one in math class because I preferred the word problems. Most just wanted the formulas laid out to solve. I had one memorable day when I was the only one who got the correct answer and this exercise required class consensus. I learned how tough it was to fight peer pressure with everyone else telling you a different answer was the correct one. I managed to convince one other student before the teacher declared I had the correct solution. You never see formulas laid out in real life, it will always be word problems. I also scored 100% on the test.

I agree there was a logistical component to the problem that I pondered as well, while I was doing the math. I pondered that 2 people would be trapped when it stopped, but that would be if the were 4 divisions, with 3, they'd still be able to squeeze out single file, so I went with the accepted answer.

I looked at the first problem only, so apologies if I am jumping to conclusions, but this question was what I expected. I am rather fed-up with people calling basic numeracy and trivial logic problems 'mathematics'. OK, you can solve some of these problems with elementary algebra, and they do involve 'mathematical' skills of some sort. However, as someone who has studied quantum mechanics I would say that mathematics is solving things like differential equations and complex algebra. I am not saying that trivial numeracy or algebra is easy, because some people can solve these problems faster than others. However, these types of questions only test one very narrow and elementary mathematical skill. Incidentally, solving many types of equations requires as much intuition as logic. Schrodinger arrived at his wave-equation by intuitive deduction and not by logical proof. Mathematics is so much more and the most important skills of mathematics are not tested by this type of question.

I got 100%, while having a catch up with the boss :-D

I was trying speed and not fully think through the answer, failed to be very fast and got 80 percent. I still can't believe I blew it on engine capacity. I remember taking a class and I had complete contempt for it. It was required, I couldn't get out of it, and it wasn't teaching anything I didn't already know. One test, I got an 80% because I'd missed a question. I couldn't see a single thing I had done wrong. I asked if someone had gotten that answer right. In the class of 30 one student had gotten it right. I asked to see it and we exactly matched, step by step. I agreed to not say anything if our answer turned out to be wrong, but when the teacher came in, he was really unhappy because in three classes and 90 students, one had gotten an 80% and no one else had gotten above 40%. When he got to my "wrong" answer, I made him change the score to 100%. Since I completely ignored what he said during class, I have no idea if they did so badly because they didn't do their homework or he couldn't teach. I do have to admit that attitude was my downfall, because they finally got into subject matter I didn't know and I was so set in my ways, I totally blew that test.
