The student had read the time on the left clock wrongly. It should be 2 pm not 12.10 pm.

From 2 pm to 3.15 pm the long hand moved 1 and 1/4 circles.
So altogether there are 5 right angles.

Hi Andrew,


mathsparks is right.

Mr Ng bought three times as many badges as toy cars and spent $144 in total. He spent $84 more on toy cars than on badges. Given that a toy car cost $10.4 more than a badge, what was the cost of the bagde?

Ok can anyone confirmed that this method below is allowed and the child will be awarded full marks?

Let N be the number of cars and B the cost of badge

3NB + N(B+10.4) = 144


N(B+10.4) -3NB = 84

Solving above
6NB = 144-84=60
NB=10

From 2nd statement
NB+10.4N-3NB = 84
10.4N= 84+20= 104
N=10; B=$1

Also if we don't use Dharma's method or the algebric method, is there a model method?

Many thanks in advanced.

Here is the model method:

Emelyn:

I mean in the model, you drew Ali and Billy having the same number of cards.


I don't understand why.

Maybe I am really slow..... :?

Hi Emelyn,
You can draw a smaller unit excluding 28 too. See if you can understand my MD better.

Thank you for your time.


1) Mr Lim spent $1496 on some comics and dictionaries altogether. The number of comics bought to the number of dictionaries bought was in the ratio of 3 : 2. A dictionary cost $4 more than a comic. The total cost of the comics was 20% more than the total cost of the dictionaries. Find the cost of a dictionary.

Q2) During a warehouse book sale, Sally spent 62.5% of her money on 24 books and 18 pens. She also spent 25% of her remaining money on 18 files. Each pen costs 8/9 as much as the price of one book. The file costs $7.80 less than a book. Find the total cost of one book and one pen.

Hi all RGS Moms,


Moi not from RGS… of course will never able to understand the sentiments that all you have.

I have a friend who is old girl of RGS and would like to share her story.

Both of us have children of the same age and few years back, both were going through the same rigorous trial of PSLE.

She had a miserable year of crying because she kept wondering why her children can’t be like her - love to study hard for exams and kept comparing them to her RGS friends whose children were doing well like their moms. She said she felt shameful whenever she had class gathering when they talked about their children’s achievement. (BTW, her child got 240+)

I just feel sad for her and her children because they are missing out the best time of their life - bonding and sharing.

It is good to motivate your children to do well. But if they have other talents or interest, let them be. Through supporting their interest, they know you are putting them themselves as your piority not their achievement for you as your piority. In turn, they are willing to work hard to make you proud of them. If a child is being push too hard, he may not want work hard just to spite his parents.

Hi to All Moms & Dads,


You have worked just as hard as your children.
Whether your children have achieved your expected result or not,
they have put in their best.
Continue to encourage them, they will appreciate your love and concern for them.
They will find the strength to carry on for the next lap!
Three cheers for yourselves and your children.
Enjoy your holidays!
