All About Math Olympiad Training & Questions

[Absolutely Bo Chap]

Kebun Baru CC is organising a 2 day Mathematical Olympiad workshop from 18th to 19th March 2013, 9.00am to 1.00pm.


Here are the poster problems:

1. Let ABC be an isosceles triangle and D be a point inside triangle ABC.
AB = AC = BD
Angle BAC = 90 deg
Angle ABD = 30 deg
Find angle BCD.

Ans:\t30 deg

2. A group of workers need to mow two fields.
• The area of the large field is twice the area of the small field.
• On Day 1, all the workers mow the large field.
• On Day 2, half the workers mow the large field and half the workers mow the small field. The large field is fully mowed by the end of Day 2.
• On Day 3, two workers mow the remaining of the small field. The small field is fully mowed by the end of Day 3.
How many workers are there?

Ans:\t8 workers

3. 2 friends are having a conversation.
A: The product of the ages of my 3 children is 144.
B: What are their ages?
A: The sum of their ages is the number of books on the shelf.
(B counts the number of books.)
B: I still do not know their ages.
A: Oh, yes. I forgot to mention that I do not have twins.
What are the ages of the 3 children?

Ans:\t3, 6 and 8 years old

Here is the banner problem:

4. Let ABC be an isosceles triangle.
Let D be a point on AC.
Let E be a point on BD.
AB = AC = BD = CE
CD = DE
Find angle CDE.

Ans:\t100 deg

I think the banner problem is the most difficult.

HI I think the NMOS is likely to be on first week or second week of July. They are usually held the first Wednesday after the school reopens on Term 3.

Hi,

Can anyone share what are the benefits of joining the P6 Math Olympiad Training in school? Not so much on the competition. More on what they have learn from the training. Am deciding if I should let my child participate. Thanks.

There are usually 3 types of questions that are contained within the Primary Maths Syllabus and they revolve around A) Knowledge B) Comprehension C) Application.

Maths Olympiad Training normally trains the students to apply their knowledge of maths in various situations. Hence the benefits to the child for a good MO programme is flexibility of thinking, enhanced problem solving skills and ability to apply prior knowledge to solve problems creatively.

Any proposed solutions to the poster problems and banner problems?

[Absolutely Bo Chap]

Problems 1 & 2 can be solved, though with a bit of efforts. Problems 3 & 4 remain challenging.

For Question 3, is the number of books shown on the banner?

[Absolutely Bo Chap]

No, the number of books is not given. It is a poster problem … the banner problem is Problem 4.
