There should be no need of trial and error in the test.

In year 7 i learnt sht. I kinda was thinking something along the lines of that but not the same, meh but I got the answer out anyway.

Didn't you learn factor trees in year 7? And if not it isn't too difficult to know that 13 is a factor of 117 and then (117-13)/2 =52.

It was question 40 on the H paper so you might not have had it. I can't really remember much about it so I'm being very vague...

did the H paper have the question regarding 'a+b+c=117'. If not, you may have done another paper, I don't recall a question about a rug, or it might just be my bad memory.
