How are you in maths?

[Tomz_KV]

are these not real test question? Tell me about it. :((

ok how did I miss 2. I think the answer to # 7 is wrong. I chose what they said was the correct answer but.. You could not Physically have 6 people coming in at the same time. 4 at the most. I think # 9 was wrong also. I could have sworn I chose the smallest number. Is 26.5 larger or smaller than 26.58 ?

It is an adaptive quiz that takes into account your answer as well as how long you take to answer. It stopped after 10 for you because it didn't think you can handle any of the harder questions. :)

Ah, was blocked for me anyway, will have a look when I get home!

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.

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.

100% no calculator or pen and paper, cmon guys this is primary school stuff.

Scored 90/100. :cool: (Inspite of using the calculator after Q5 :^) )

Taylor Series Expansion is Maths. This just Arithmetic, chaps.

The less you answer the higher the mark you get, this will decrease the possibility of errors.

Yep, I almost missed that one, too. But then I'm used to specifications arriving late ;P

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

[Pete81E]

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

[greldak]

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.

[Stefan_Lang]

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

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!

[Stefan_Lang]

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:
