UKMT maths challenge...

Just a thread for discussion mainly for after the test but thoughts are welcome. I'm doing the senior one on Thursday, we have a little bet in our maths class to see who gets best in school (I know, we are too cool for school) :biggrin:

Just checked a past paper on the website and it looks at the same level as Junior and Intermediate :confused:

Err... much harder than intermediate.

Has anyone got a good resource for practising? I haven't bothered for 6 years, but for my last time I want to make sure I get into that BMO ^^

If anyone beats me I will change my signature and avatar to anything they like for a number of days equal to the number of points they beat me by.

Yeah I'm doing it tomorrow as well - I find it impossible. Our school gave us all the papers from 2002 to 2004 (with solutions). I personally found these the hardest:

Oh you're much better than Shaun, Speleo. I should probably make ur font bigger.

mathsfight GO!

Woah people this thread's getting out of hand, everyone calm down :wink:

Other than the one paper on the official website (which doesn't even have a amrk sceme, where could I get papers with mark schemes?

And what are the mark boundaries for each certificate? (Out of 100)

Right well I'm blaming my performance today on my food poisoning. I definitely got 17 questions right which gives me 93 points and most probably a gold certificate but I found it too timeconsuming and couldn't even look at the last 5 questions. I missed out the squares question (Q3) and the sin cos (Q16) and even though I spent 15 mins doing the working for the trapezium question (17) and thought it was right, it wasn't. Btw did anyone get 200 for the london eye question? I just went with the closest choice to 200 which was 100 but something must have gone wrong there.

Protip: read the questions properly D:

Would anyone like to share their solution to the one about the five dots and three colours, where no two adjacent dots can be the same colour. I found that one quite annoying.

I put 500 for the one about the london eye. I'm not very confident though.

For the 5 dots and 3 colours one I got 48. I also got 500 for the london eye question. Fingers crossed peeps!

you are right about the london eye...

start at the centre, the one in the bottom right must be a differnet colour. Keep these two colours fixed.

There are 2 combinations in which the centre colour is in both top right and bottom left (with the other 2 colours top left making up the 2 different combinations.)

There are 2 combinations in which the third colour is in top right and bottom left(with the other 2 colours again in the top left making up 2 different combinations.)

There are 2 combinations with the bottom right colour in the top left. (With the central and third colour swapping places in the top right and bottom left)

This gives 6 combinations.

There are 6 different ways of arranging the first two circles.

6*6=36

What about Q20? I worked it through and 0.3 fell out. I'm not very confident though.

EDIT:hmmm after working through again, it appears 0.7 is the actual answer. Oh well
