Test questions for 30th April

Q2 My Dog ate my homework!

I fell asleep while doing my Math homework.

When I woke up, I saw my file open and my dog is eating my homework!

I fought with it and managed to take back some parts of my HW!

And this is all that remains.

Please help me to reconstruct my HW. I can't even see the question. Only the diagram and the final answer remains!

Rudy is thinking of buying a European car that is being offered at

S$145 000, including COE. He has a few considerations before he

decides whether to buy.

Down payment is 20%.

annum for a 7-year loan.

Road tax of S$1 250 per year.

Car insurance of S$1 500 per year.

Financial Transaction Online test : Guru's solutions

Common errors:
Q12 (12 got this wrong)
A man borrowed $ P at 10% interest compounded annually. Determine P if the
compound interest for two years is $ 6615.
P + 6615 = P (1+ 10/100)^2 ---- this is a compound interest question!
P + 6615 = P (1.01)^2
P + 6615 = 1.21P
0.21P = 6615
P = $31500

Q3 (10 got this wrong)
clues: calculate balance after paying deposit.
i.e. 80% x 145000 = $116000

Use this balance to calculate total interest for 7 years.
Then add to balance. (This is the total repayment amount)
This repayment amount divided by 7 = repayment for each year.

Repayment for each year + road tax + insurance = Total cost per year

Total cost per year / 12 months = monthly repayment.

Q18In what time will $1500 amount to $1770 at 9% per annum simple interest?
$1770 - $1500 = $270 (interest)

using I=(PRT)/100 formula, you should be able to get

270 = (1500 x 9 x time)/100

Then work out the time.

Your answer i is incorrect Your Score: 0
Mrs. Ong wants to purchase a refrigerator from a shop that offers a discount of 15% on the retail price of $3000. If the delivery charge is $25, how much will it cost Mrs Ong to buy the refrigerator and have it delivered?
discount=15/100x3000
=450
3000-450-25=$2525

Did you read the ST today?

New course at Poly: Designing Xbox games.

If you are an avid gamer, this is meant for you!

A simple percentage question

Your Guru has just booked a car.

The cost of the car is $52500.
She has placed a downpayment of $5000.

1.
How much will be monthly repayment be if she took a 5year loan at 2.85% p.a. simple interest?

2.
In the total price of the car, one component is the COE rebate of $5000.
It works in this way: If the COE for that month falls below $5000, the excess will be refunded to your Guru. (E.g. if COS costs $3000, she gets $2000 back) If the COE costs more, she does not have to top up any money.
Find the total cost of the car (inclusive of interest) if the COE price is
a. $7800
b. $2800

To know which car.... google for it. Suzuki SX4. You all will only get to see it next term, cos the car will only be available in late May.
