Re: How did people go in the maths comp today?
I would have done it by finding a pattern since I don't know any advanced method
Corresponding last digits of various powers to 8
8^1 = 8
8^2 = 4
8^3 = 2
8^4 = 6
8^5 = 8
By this, we find that the last digit repeats every 4 powers
8^2009 = 8
And...
Re: How did people go in the maths comp today?
It was something along the lines of:
The reciprocal of 4 numbers add up to make a total of 19/20. 3 numbers are in the ratio of 1:2:3. Find the sum of the 4 numbers.
There could have been more detail but if there was, I can't remember
Re: 2009 AMT Mathematics Competition
Well I knew the last digit of the answer had to be a relatively large number because it is an Ascending number. So I assumed that the last digit of n had to be 8. (6*8) = 48, has 8 as a last digit.
From that step, I pretty much used trial and error of 3...

The Westpac comp yeh?
Yeh, I did the Senior Divison and I found that it was really difficult compared to past senior papers.
I'm confident I got 26 and 27 correct.
Re: How did people go in the maths comp today?
Umm, I remember 27 so I'll try explaining that one.
27. A number is called Ascending if the digits are increasing. Eg. 123 and 2356 is ascending but 749 or 7799 is not. Find a 3 digit number that is Ascending and also has the property that 6n...
Re: Australian Mathematics Competition
I reckon more like 70-80 for yr 12 and 60-70 for yr 11. I reckon the Senior Division was harder than past Senior Divisions
Re: How did people go in the maths comp today?
I had to do the Senior Paper although I'm in yr 10 (accelerant). This is what I think I got:
1 - 10: 30 marks
11-20: 24 marks (Really hard for some reason =/)
21 - 30: 10 + 13 marks
= 77 marks.
What does this become around?
Hmm, I reckon if you want to do a Law or Combined Law degree, then Legal Studies is essential. Doing Economics wouldn't hurt either. As for your subjects, it seems as though you want to do subjects that prepare you very well for uni so a recommendation would be doing both Legal and Eco by not...
