for the ans:351 the question was abt chairs...someone arranged chairs in rows of 9. he bought 6 chairs and arranged the chairs in rows of 7 and had 12 more rows. how many chairs are in the hall at first? (i think?)

My answer is 357. I used algreba but it took many steps . Assume that number of chairs is x.Try to make two number sentences equal to each other and try to eliminate one equation by minusing it out from the equation that is greater in value.

I used the same method. I arrived at x=39. Then, i 39x9+6=357.

my ds' answer is 'deceitful' also..

I think the later qn is a little 'tricky'..my ds said initially he put 'substantial' then later chance to 'pronounced'.. :roll:

I think a lot of kids torn between \"pronounced\" and \"substantial\". Good for your DS :rahrah:
I hope this was the only mistake my DS made

Hi, my name is Shash. I am taking my PSLE this year. According to my teacher, the answer is pronounced but substansial could be possible too. Ultimately, substantial is for stuff which can be quantified, making pronounced the more accurate answer.
