285478 2004-10-28 08:41:00 Speaking of how badly NCEA questions are worded....

Got this today (roughly):

John bought a car. He paid a 30% deposit and borrowed the remaining 70%. He will pay the money back using two methods:

1) He pays his parents $45 a month for two years.

2) He has a deal with the card dealer that means he doesn't pay anything for two years, after which he pays a lumpsome which includes 10.5% interest on the amount owing at the start of the first year, and then the further 10.5% on the amount owing at the beginning of the second year. The lumpsome he paid was $2992.

What was the original price of the car?

Now, one would wonder where 1) would enter into it.

If he has a deal with the car dealer to pay back 70% of the car (the amount he borrowed), then why the hell does his mum enter the equation?

The answer was (amount he paid his mum + amount for car pre the interest)/0.7.

No one in our class understood this, not even our teacher.

Maybe he borrowed the 30% deposit from his parents?

They are quite good at leaving out "relevant" information and leaving you to use your imagination sometimes. ;-)

I presume you want a private tutor? As you say you can't study much at home.... and according to your profile.. you're in Samoa!!??!?!/

Please confirm what year level you are and where exactly you are in the world....

Disclaimer: I don't mean any offence. Just expressing my view as many forum users have said is allowed :p

For a starter, the teacher needs to sacked. Even my third form brother did it in less than two minutes! [yes he did have a calculator]. If this is what your complaining about, then don't even think about IGCSE. Personally, I see NCEA questions as being great, real life problems.. etc. IGCSE has questions usually 8 parts wrong. If you stuff it up at the start.. you're stuffed. They mislead you more than anything else.

This is soooooooooooooo easy! Look....

1) He gets $45 from his mum for 24 months (2 years)... so
45x24=$1080
2) He pays $2992 in the end after two paying two lots of interest... so
2992/1.105/1.105=$2450.40

So in total, 70% of the cost is made up of $1080+$2450.40=$3530.40

Now, to find 100% you go $3530.40/0.7=$5043.43

Bingo! I don't see whats so confusing!

I can understand why your class can't understand.. because your teacher can't! The only negative thing about NCEA is its marking system, and international reputation so far. Ha... ! IGCSE with that kind of teacher? Dream on....

I shall go enrol for teachers college for next year.... muwhahah :D
