thought the last question was hard, i think i got most of that one wrong. lol and im doing mathematics next year.
50."this woman is 40 years, in 10 years she'll be younger than this other dude by 20 years. How old is that dude right now?"
epic fail -_-
I was so tempted to write "because she's a woman".That 10% crap yeah i was lost LOL
i seriously had no idea for the probabilty question too
i just wrote less people on their team
and athletic ability
SOo wrong...
i think i put 50 for that guy but i remember the woman being 30 or sumthin or was it 40"this woman is 40 years, in 10 years she'll be younger than this other dude by 20 years. How old is that dude right now?"
epic fail -_-
Nah, it was 30.think it was 40, i put 60
Winnah!!yeah it was 30. answer was 50.
Most people in my school didn't. I finished with like 5 minutes.did anybody finish non-calculator? multiple choice was easy but i didn't even finish non-calculator
qtf.yeah it was 30. answer was 50.
I got this as well but bit different in the end.i got this n³ + (n-1) ³ + (n-2) ³ ... 1³..
is it the same thing?

yeah i had to miss out the second last question from section 1 coz i didn;t have enough time , but what really killed me was that i had like 20 minutes left for section 2 but i couldn't go back to section 1 to finish coz we weren't alloweddid anybody finish non-calculator? multiple choice was easy but i didn't even finish non-calculator
really, this question said that the person bought 10% more tiles then needed.wat did every get for that tile one the last one how does it equal 1980 and something about 10 percent extra for breakage my equation was...
178.2 x 0.09 = 1980 ....i was so glad that i got it rite 2 marks in the bag
the area of the rectangle is 162 +10%[16.2]=178.2 and the tile is 0.09^2
so ye i just did 178.2 x 0.08 = 1980 soo happpy
Same boat as you.area of tile = 0.09. area of rectangle = 162.
162 / 0.09 = 1800
then take 10% and add
1980
i finished non-calc with around 5-10 minutes left. idk why people found it so hard (except for 24, that was pretty challenging lol)
