I try...

1567+865=2432 (total no. of chairs)
2432-769 red chairs=1663 blue chairs

That's my guess at how most kids will answer this.


BUT i find the phrasing open to interpretation.

-- After he had painted 1567 chairs, Mr Yeong still had another 865 chairs to paint. Given that he painted 769 chairs red, how may chairs were painted blue?

Seems like the 865 chairs is a red herring that should be ignored, since Mr Yeong had actually painted only 1567 chairs. So out of that, 1567-769=798 were painted blue.

What was the given answer?

What is your answer if u are the student, CayennePepper?
1663 or 798 :evil:

Hmm... ... interesting

If this is a GEP type qn, answer can be 798 because \"Mr Yeong had actually painted only 1567 chairs\" and should ignore the \"865 chairs\" as yet to be painted. If this is a usual school exam question, answer may be 1663 as i believe is answer by most.

Well, open to interpretation lah! so what is the answer?

i went around asking kids and interestingly the ones good in EL/math all said 798 should be the answer.

Thanks v much for all your replies. Given answer by school is 1663. 1663 is full 4 marks while 798 is only 1 mark (for consolation!). DS and friends in school usually good in Maths also puzzled.

:nailbite:[/quote]If this is a competition question then u are correct!
However, this is a normal P3 Math question right? So the answer should be 1663.
Nowadays, this became quite a common case in P3 (even P4) maths questions already. I have no idea why didn't the questions setter put more effort in sentencing P3 Maths questions.

Anyone can help to interpret a problem sum in my DS SA2 Maths? I find the question quite confusing:-


Mr Yeong had to paint the chairs in the hall red or blue. After he had painted 1567 chairs, Mr Yeong still had another 865 chairs to paint. Given that he painted 769 chairs red, how may chairs were painted blue?

Thanks in advance!

Hi

The way I would go about thinking is this: He already painted 1567 chairs, and he had 865 more to paint. If he painted 769 chairs red in total, then the answer would be 1663. But if he painted 769 chairs from the 1567, then the answer should be 798. Answer's open to debate. Ambiguous questioning...

The school teachers had decided that 798 is also an acceptable answer. DS was so happy!
