My logic as follows:greenfinger wrote:a)Each of the three cards is printed with a different whole number.The smallest number is 25.Two cards are drawn at a time and the numbers on the cards are added together.The sums are 56,68 and 74
What is the largest number on the cards?
PLs anyone guide me ,thank you
56 is the smallest added number, hence 25 should be part of 56.
So 56-25 = 31 is the next card.
The last card would be 68-25 = 43 (since 68-31 = 19 <25)
Test it on 74-43 = 31
So the 3 cards are: 25, 31 and 43.
Btw, what level is this question?

After he sold 2/5 of the tables and 5/8 of the chairs, he had 459 tables and chairs left.
How many tables did he sell?
This question touches on simultaneous concepts.
If a student is familiar with SE, he/she may use it.
If not, he/she may solve the two equations pictorially or use the “Alphabet Method”
Tables sold ------ TT
Tables left ------ TTT
Chairs sold ------ CCCCC
Chairs left ------ CCC
TTT + CCC ------- 459, hence T+C ------- 153
TT + CCCCC ----- 534 (993 – 459), therefore C -------- 76
T ------- 153 – 76 ------ 77
Tables sold ------- 2*77 ------- 154.
Best wishes

Doesn't look like a primary Maths questions from syllabus. Seems more like a Maths Olympiad type fo question to me.ksi wrote:My logic as follows:greenfinger wrote:a)Each of the three cards is printed with a different whole number.The smallest number is 25.Two cards are drawn at a time and the numbers on the cards are added together.The sums are 56,68 and 74

Hi
Please help with the following:
Jack read 18 pages of a book on Saturday. He read 5/9 of the remainder on Sunday. He still had 1/3 of the book left. How many pages are there in the book?
I really don't know how to tackle fraction kind of question. Please advise how to improve on this?
Thanks a lot.

Re: Q&A - PSLE - Math
To all,
Please help!
Q. The movie tickets at a cinema are priced at $8 for adults and $5 for children. The number of adult tickets available is 1 2/3 times the number of child tickets. 9 out of 10 adult tickets and all the child tickets were sold. The ticket sales amounted to $4,590. How much more would have been collected if all the tickets were sold?
Thanks!
Regards
