I picked "A" but without looking at the chart again I can not be sure what the numbers were.
If I remember correctly the last 2 in the chart were larger than the first 2.

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!

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.

Scored 90/100.

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

Sorry, missed "down at twice that speed..." Oops...

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.

Thanks for posting this, it was a welcome distraction. Of course the 10/10 helped (yes, I used a calculator, why do the heavy lifting yourself if you have a crane handy  )

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 refuse to take part is such a travesty. Imagine being tested by a country that pluralizes Math and sells weight in stones in monetary units of pounds ... it's just crazy.

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

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 had two wrong. With the first question, I resolved to not actually do the math, just answer with the first thing that comes to mind. (Too simple to take seriously.) I really have no idea how I managed to get the engine capacity wrong.

This year I have a gift coupon of 157.50 GPB in amazon.co.uk and 50 Euro in Amazon.de valid till this year end.
Mrs Super said she doesnt need it but prohibited me from paying more than 10 euros Extra over gift.
Little Super said she want some electronic aka tablet stuf to play games.
So what choice I have?
cheers,
Super
