        Before being allowed to use one rotted my brain I was able to do problems like 98*76 or 9*876 in my head faster than anyone could tap the buttons on the idiot box and win about half the time with problems like 98*765 or 9*8765. If I wanted to show off I could do problems like 9876*54321 too but had no chance of beating a button masher. My informal test for how clueful grade school teachers were was to see how long it took before they realized that if they were going to offer a prize for a basic in class math-game (generally flashcard speed) that unless they offered them for the top two spots they might as well just save some time and give it to me at the start of the day.

        Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.

            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. :)

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

              That's the only one I got wrong, as I missed the "in cm" bit at the end. Not really math, more reading. Iain.

                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.

                      10/10, as usual with these types of questions, the maths is fairly easy. It is reading and understanding the question that tends to trip folk up because they rush, then apply the wrong logic.

                      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.

                        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:

                                        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.

                                          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!

                                          GOTOs are a bit like wire coat hangers: they tend to breed in the darkness, such that where there once were few, eventually there are many, and the program's architecture collapses beneath them. (Fran Poretto)

                                          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.
