Sorry the table come out a bit weird

Is the answer A) Food?

What I did was get the CPI% as a decimal (i.e. for food 0.3) then get the CPI as a decimal from the base year so for food (1.1) then I did 0.3/1.1
Do that for Health, Housing and Clothing as well and I think (A)'s the right answer?

Yeah well that explains it, the 2010 HSC paper for eco was ridiculous!

 

[BoredDude]

Food - 30% of 10 = 3
Health - 10% of 30 = 3
Housing - 15% of 25 = 3.75
Clothing - 20% of 20 = 5

Therefore, d.

Food - 30% of 10 = 3
Health - 10% of 30 = 3
Housing - 15% of 25 = 3.75
Clothing - 20% of 20 = 5

Therefore, d.

Yep that is the correct logic.

I've seen a few similar questions. It's important to note that "base year = 100'.

It was harder than most years, yes! I'm predicting a fairly good paper for you 2011-ers who are doing the exam AS WE SPEAK (and hopefully nailing it!)
