Hi Tianzhu,

My DD teacher has taught her class to use this \"gap and different\" concept to tackle this \"kind of problem\" and she is stuck with this question and couldn't understand why is it so...

Hi DinoKing

Good Afternoon.

You’ve used an interesting term “this kind of problem\". With this, it only means one needs this kind of strategy to solve this kind of problem.

It’s good to know that there is always more than one way to solve a problem.

Maths questions are not foot prints on concrete which has hardened but foot prints left on sand which can be easily erased. Questions may look similar but tweaked to make them more interesting.

“Gap and Difference” concept may be applicable to a range of questions but it cannot be applied to your question.

However, Multiples Method may be applied to questions which could be solved by GD, for example the you may use the Multiples Method to solve the Pokemon question.

Meanwhile, take a look at these questions.

Q1 and Q2 are common question found in primary maths, you may use Multiples Method or Gap and Differences Method to solve it.

Q3 is a similar type of question but given a slight tweak. It is quite an interesting one.

Q1) Xie Ming Ming had some oranges and some boxes. When she put 12 oranges in each box, she had 35 oranges left over. When she put 15 oranges in each box, she was short of 55 oranges.
a) How many oranges did Xie ming ming have?
b) How many boxes did she have?

Q2) A box of apples is shared among some people. If each person gets 5 apples, there will be 4 apples left. If each person gets 6 apples, there will be a shortage of 5 apples. How many people are there?

Q3) Guo Cong Ming distributed a packet of sweets among a group of pupils. If he gave out 11 sweets to each pupil, the last pupil received only 6 sweets. If he gave out 8 sweets to each pupil, there would be 34 sweets left over.
A. How many pupils were there?
B. How many sweets were there?

Hi all,


Appreciate anyone free to solve a maths problem as follow:-

Some apples and oranges were packed into blue and red boxes. There were 12 more blue boxes than red boxes. Each blue box contained 120 apples and each red box contained 150 oranges. Given that there were 120 fewer apples than oranges in total, how many apples were there?

Many thanks,
Stary :?
