Erm, any reason for asking?

Hi

I found some of your questions quite different from those from past years papers.

Take for example, Q1 in your last post, this is the first time I am seeing it.

I feel it’ll be beneficial for current students to take note of new trend questions, that’ s why I am asking for the sources .In this way, students may be alerted to pay more attention to them.

However, if you’re uncomfortable to reveal them, it’s perfectly alright.

Best wishes

(3). Peter and Tom shared a number of books in the ratio of 3:4. After Peter and Tom bought another 19 books and 2 books respectively, the ratio becomes 4:3. How many books did Peter have at first? (Using External Transfer Concept)

Thanks

Hi

You may use “Units and Parts”

At first
Peter: Tom ------ 3 units:4 units

Change
Peter: Tom ------ 19:2

In the end
Peter: Tom ------ 4 parts: 3 parts

Equalise the parts or cross multiply.

3 units + 19 ------ 4 parts
(x3)
9 units + 57 ------ 12 parts

4 unit + 2 ------- 3 parts
(x4)
16 units + 8 ------ 12 parts

9 units + 57 ------- 16 units + 8
7 units ------ 49
1 unit ------ 7

Peter ------ 3*7 ------- 21

Best wishes

Hi,

Appreciate if anyone can help me the below ques:

1. Adeline has $40 which is made up of fifty-cent and twenty-cent coins. There are 50 fifty-cent coins. What percentage of the number of his coins us twenty-cent coins?

Thanks

Hi Ngserene617,

We just need to list down the facts given.

Total money Adeline has = $40
fifty cent coins = 50
Value of fifty cent coins = 0.50 * 50 = $25

amount of money in twenty cent coins = $40 - $25 = $15
Number of twenty cent coins = $15/0.2 = 1500cents/20cents = 75

Total number of coins = 75+50 = 125

% of twenty cent coins = 75/125 *100 = 60%

Hope this helps.
