Hi Champion,

Long time no see.
I think ksi's answer is correct. Mine has typo error at the working; '102' mis-type into '120'. Had gotten child to check my model, but didn't get him to check my working. :oops: sorry.

teh-oh...no problem..... I actually withdrew my solution and wanted to do a check when I saw it differed from yours but too late... So you see...I also think I can make mistake cos we don't do it daily. What's important is we are all willing to share. :celebrate:

Hi ksi,
So embarrassed. The first time I attempted to use Excel to draw a model. Got child to check model to ensure I drew it correctly, but made the careless mistakes that regular P3-ers did :oops: .

1) A number is a multiple of 3. It is between 10 and 40. It is also a factor of 45. What is the number?

is the answer : 15?

2) There are 943 apples in Box X and Box Y. There are 785 apples in Box Y and Box Z. How many apples are there in Box X than in Box Z?

Hi

1) yes.

2)
[Box Y][**Box X**] = 943
[Box Y][*Box Z*] = 785
So [**Box X**] - [*Box Z*] = 943 - 785 = 158
There were 158 more apples in Box X than in Box Z.

cheers.
