Maths Isnt Fun:

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.

However, we felt that paper 2 was okay

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

Hi, any idea what the ans:351 question is about?[/quote]



A school hall arranges some chairs in 9.

In a concert, Mr Tan brought in 6 more chairs and arranges them in rows of 7. This time, he gets 12 more rows.
How many chairs were there in the concert?[/quote]

My DD said the question was \"how many chairs ARE there in the concert\".Therefore, she interpreted it as how many chairs are there NOW, hence she added 6 chairs back to 351. her ans therefore was 357.
