When she came back, she found that her baby daughter had doodled on the paper.

Please help her reconstruct the question.

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!

A Math Test results

Your recent A Math Test scores:



Trend--- There are some improvements.... some single-digits are improving.... (e.g. Charlene, Wu Pan)

A few who failed the previous tests are doing better too... e.g. Da Qiang, QiQi, Shu Wen.



Well done to Xue Chun and Bjorn!

all topics. Refer to TYS for sample paper 1.

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.

Topics for A Math Block Test 3

These are the topics for A Math Block Test 3:
