Title: Module 4 Business Maths Discussion: How'd you guys find it?
Post by: sam.utute on November 01, 2010, 02:38:09 pm
It doesn't seem like my VNers do Business Math. :)

Overall, I found it pretty easy, with the only tricky question for me being Q5.
I did flat rate dep'n, before realising it's probably asking for reducing balance.

:D

Those were my answers.

question 8 i got E
I'm pretty sure it was B.
40000-22000 = 18000
For three years so:
18000/3 = 6000
6000/40000 x 100 = 15%

I interpreted question 5 as being flat-rate depreciation. So I'm wrong!?

i got the same as you.

q5 i think "20% of its value each year" means reducing balance.

but not too sure, nevertheless wrote that down.

Yeah, I originally did it as flat rate, and when I finished the paper I realised that there were no reducing balance questions. So I redid that question as reducing balance. Lucky!

I found it relatively easy, but i think, i like many others effed up on Q5 the goddamn reducing balance DAMN YOU VCAA!!!

I made a stupid stupid mistake on 8. I went for A and not for B. I first had B and then changed it since I thought wait it might be four years. Blahh kicking myself now stupid mistake -__-, Hope i can still get a 40 or close to it.

guys Q5 30000*(.8)to the power of 3 so C
Q6 is MINIMUM  MONTHLY BALANCE so 1450*1/12*3.6 divided by 100 so A

I thought about using the TVM solver for that question but having not be familiar with this topic I had only previously used it to answer the PMT (I decided to do this instead of Trig last night).

I ended up going 4000 x 1.05 + 800 = 5000
then 5000 x 1.05 + 800 = 6050 which gave me E.

I am guessing you use the TVM solver to work out q8 as well? I couldn't figure out how to do that one either. Other then those two I had all the same answers as you.

You needed to divide the 5% p.a. by 4 to get the quarterly interest rate. Other than that, your working is correct.

Nah, TVM is useless for Q8.
Basically, 40000-22000 = 18000
That's how much depreciation over 3 years, so that's 6000 per year.
Express that as a percentage over the cost price:
6000/40000 x 100 = 15%

By far the easiest module, way easier than the previous years. I went through the nine questions in 5 minutes, no joke. Everything was pretty much explanatory D:

Ah of course, what a silly mistake.

Ah cheers, pretty easy question as well.
I didn't really know how to approach this one so I did 40000 x each of the interest rates but another silly mistake by me was reading it was a flat rate.

Anyways, thanks for showing me how it's meant to be done.

I got a few differences
Q9-B and Q5-B
can someone explain these answers.

Q9-B and Q5-B

Q9 is above.

To get the answer to Q5 I did:
after 1st year = 30,000 x 0.8 = $24,000
after 2nd year = 24,000 x 0.8 = $19,200
after 3rd year = 19,200 x 0.8 = $15,300 = C

You would have done the first year correctly figuring it out it drops by $6,000 but then you have to get 20% of the number after this first year which is 24,000 rather then multiplying $6,000 by 3 then taking it away from $30,000.

Guys i think question 5 is B....
The file server depreciates by 20% of 'its value' each year

doesnt 'its value' = 30000 so since 20% of 30000 = 6000

30000 - 6000x3 = 12000 = B?

30000 - 6000x3 = 12000 = B?

i wnent with C because it says "its value each year"

so i went 30 000 X 0.20 = 6000
30 000 - 6000 = 24 000
24 000 X 0.20 = 4800
24 000 - 4800 = 19 200
19 200 X 0.20 = 3840
19 200 - 3840 =
15 360 = C

I hope it's right, its the difference between a B+ and an A for me basically

Post by: zxcpoi123 on November 01, 2010, 09:49:25 pm
It's pretty confusing whether it's " its value....each year " or " its value of each year"

i hope they figure something out or just give everybody a mark :P

win win for both of us xD
