Stuck on q1, 4 and 6 from the 2001 HSC exam. Pretty sure I know the methods but can't seem to get the answers. Any ideas?
Q1.
1cm = 10 companies.
1987 = 49 out of 66 NZ Owned = 74%
1997 = 39 out of 92 NZ Owned = 42%
74-42
= 32% --> C
Tip: I had attempted to calculate percentage change for just NZ Owned companies (ie, how many more NZ owned companies were there in 97 than 87, but the Question actually asks for the change in the percentage of NZ Owned Companies from 87 to 97 in comparison to TNCs.
Q4.
Area of Queenstown = 4 x 3 (Approx) = 12 cm squared.
1cm2 = 25000
Therefore 12 x 25000 = 300000 --> B
Q6.
Distance by Road = 12cm = 12 km using scale of 1:100000
At 40km/h, 12/40 = 0.3 hrs
0.3 x 60 = 18 minutes --> C
