Another P6 question and I wonder if the question is correct;
Mr. Wong had 207 apples and oranges. After he had sold 50% of the apples and 40% of the oranges, he had 45 more oranges than apples left. How many fruits did he have left?
Thank you.

Hi

I guess you just want to confirm the answers.

I did a quick check, and the answers are 81 oranges and 36 apples giving a total of 117 fruits.

Hi

need help in the following questions.
a)The number of 20cents coins to $1 coins in Jane’s box is 5:4. She took out 8 $1 coins and exchanged them into 20 cents coins of the same value. The ratio of the number of 20cents coins to $1 coins became 15: 4. What was the amount of money Jane has?
I used equivalent ratio and got $35. I wondered is the answer correct.
Is it possible to use model or units method? If yes, how?

b)There are 140 apples and 200 oranges in Stall X.
There are 160 apples and 40 oranges in Stall Y.
How many apples and oranges must be moved from Stall Y to Stall X so that 50% of the fruits in Stall X and 75% of the fruits in Stall Y are apples?

Thanks for guide.

Hi,


I have 2 questions to ask.

Apologise in advance if they have been asked before. Because I don't know how to search if they have been asked before. Maybe we should have some \"header\" for each post or something... to identify the question. in certain \"naming convention\" which will facilitate searches.

Anyway, my questions are as follows :

1. 2010 P6 Rosyth School SA1 Paper 2 Qn 14

George had some trading cards. He gave 75% of them to Mary and 20% of the remainder to Charlie. He than had 140 trading cards left.
(a) how many trading cards had George at first ?
(b) how many percent more trading cards did Mary receive than Charlie ?


2. 2010 P6 Nan Hua Primary School SA1 Paper 2 Qn 18
