Gotta admit, turned over the page and had no clue for Q1 multiple choice. Is it two significant figures after the decimal point, or in general? thanks

It's in general. Significant figures is any digit other than zero and the zeroes between the non zero digits. So for example the two zeroes in 73002 are significant figures.

So the answer is 610, as the 8 next to the zero in 208.345 rounds it up to a 1.

i think heaps of these answers might be wrong?
i believe in MC 19 (which you said c) is actually A
21 should be D, 23 should be D and 25 should be D

and in short answer
holiday loading - it asks for total pay not just the holiday loading so dont you have to add the $858.20 to her four weeks pay? so the answer is $5762.20
27 c) i think is 36 for IQR
27 e) ii) should be 8:30am dubai time i think
28 a) should be 4/37
28 e) ii) i think is 193cm2
29 b) i have no idea what it should be but i got 9.09% growth a day
30 b) should be 61mbps

Couldn't Q25 be B? The diagram clearly says not to scale. How would you know the angle BCA is obtuse to be able to subtract the 70 degrees from 180

Hey! The question says, "it is known that BCA is obtuse" in it, easy to miss, your eyes jump to the diagram :)
