First, is this a multiple choice question where four options are available for students to choose?
The numbers are not too big, so it’ll not be tedious to arrive at an answer if choices are given.
If not, use “Systematic Listing”, it’s also not too tedious as we are dealing with small numbers.
The answer is 3 20-cent coins.

I really wonder why our children needs to know this. As long as they know the value of each coin and how to make certain amount, isn't fine? SighWhat is the fastest method to solve this type of question?

Hi,
Anyone can help to explain how to get the answer:
Qns : When A is divided by 5, it gives a remainder. Which is the most possible pair of quotient (Q) and remainder (R) when A is divided by 5?
(1) Q = 5, R= 9
(2) Q = 6, R = 6
(3) Q = 5, R = 5
(4) Q = 6, R = 4 -
Hi, instead of starting a new thread for your question, please go to the http://www.kiasuparents.com/kiasu/forum/viewtopic.php?f=66&t=149 thread and post a reply there.
For this question, the answer is (4). In division, the remainder can never be equal or more than the divisor.
