• Year 7-10

  • Did anyone do the Australian Math competition today?

that 3% of kids is prolly all the kids that got everything right if not like 1 question wrong

i think that i got the first 10 right, 8/9 of the 11-20 questions, 2/3 of the 21-25 and like 0/1 of the last 4, so best case i get like 87-91 and worst case i get like 76 -80

    Hey guys I did the test and I didn't find it that difficult, I managed to calculate the last 5 questions and I'm pretty sure these are the answers but I only realised after the test that these were the actual answers because I messed up the rods and the fruits questions during the test:
    26 - 880
    The question about rods - 146
    The one about trimming a rectangle - 674
    The one about oranges and grapefruit - 840
    30 - 069
    correct me if I'm wrong
    I think I'm gonna get between 95 and 110 points

      please explain each one and how u got the answer lol

      yeah like the first 15-20 questions were pretty easy though i may have gotten like 2 of those wrong, then from there it got pretty hard

      MMHS i calculated my score yesterday, i should receive 90-100 marks. should be enough for a distinction/high distinction (based on past experiences)

          is distinction/high distinction based of everyone who tries or the school

          i may/may not get highest in school

          most likely will, like a 80% chance but kids used chatgpt so idk lol

            which is just bs

            Can somebody explain the grapefruit and orange question to me?

              Chessisthebest so basically, the farmer took 120 grapefruits and x oranges. 1/10 (10%) of grapefruits look like oranges and 1/10 (10%) of oranges look like grapefruit. also 1/5 (20%) of all fruit looks like grapefruit (this incl. 90% of grapefruit - i.e. 108 grapefruits and x/10 oranges.) if we make an equation, we should have x+120/5 = x/10 + 108. if you solve this equation, you should get the answer of 840.
