# How do people fail to answer even ONE question on a BMO1 paper? watch

BMO being british math olympiad. (something along the lines of this) http://www.bmoc.maths.org/home/bmo1-2005.pdf
I heard the modal score for people on BMO1 was failing to answer even ONE question? How is this even possible that people are so stupid? The first question to EVERY BMO1 paper is just trivial and a free correct mark pretty much. I had a look randomly at the other questions (Question 3 in the link above) and came to the answer of 21 in less than 10 minutes. Considering you have THREE AND A HALF hours to do the whole BMO1 paper, no one should really be failing to answer even ONE question; the result should be more at the other end, people averaging a failure to answer 1 BMO1 type question per paper, at most. You have THREE AND A HALF hours to do a few questions, and these questions aren't even that hard.

BMO1 questions are so easy, how is it that people are so stupid? My god.

How arrogant can you get? Jesus...

1,2,3,5,7
I've just found 1 lol.
Off to create more eqns lol
5 is not a solution. Check your equations. 1,2,3 and 7 are the final solutions. 5 brings up a contradiction bro. As then one of them will have 0 quid when they swap and stuff.

This person probably can't even qualify for bmo.

You got q3 wrong, don't embarrass yourself and close this. The answer is n=11.

Whats the answer to Q 4? Primes in A.P
Is it 19?

I'm doing it now, it's tricky.

13. I'm more surprised by the fact that there are only 5 questions on the paper.

15. When I was 13 I could only do 1 question, the rest I had no idea what was going on. If I remember correctly the question went like this:

One number is removed from the list of integers 1 to n, the average is a value y(you are given this value) - what was the number that was removed? I think it took me 20-30 minutes...

lol i just used wikipedia lol
http://en.wikipedia.org/wiki/Dirichl...c_progressions
maybe i have a complete lack of understanding of maths and the questions themselves lol
oh yh 7 distinct primes not infinate lol hmm
p,p+1,...,p+6 ---> these and no other primes are in AP

P>=7 otherwise one term will have common multiple. S smallest p was 7. Then d was a multiple of 30 otherwise the common factor thing happens again. Then 30-180 o multiples of. 30 but rule of 180 since 187 is not prime. Then 30,60,90 aren't good cause of 187 either. Then d=150 and adding p+6d gives. 907.

That's is really impressive at that age.

Yes, provided you know how to do algebraic division, are clever enough to see how to apply it, that you perform it correctly and can do the final arithmetic without bodging it up.

If you're of the calibre to get into BMO1, then yes, it should be fairly doable (though if memory serves I recall someone who did the entire thing by arithmetic). But bear in mind that out of the eighteen people in my further maths class, only two got the answer out. 'Easy' is very much a relative term.
