What fresh hell is this maths GCSE question?

[Lex345]

Please can someone help? We have textbooks for the GCSE syllabus, teacher has not been helpful explaining this to my daughter- I don't remember this from school either-

Work out an estimate for the value of

√63.5 <->0.17

Was this an actual gcse paper?

60 x 0.2 is not 30….

It could be 63.5 x 0.17 then? So 64x0.2= 32 as an estimate, which would be 4root2 maybe?

My son who got a 9 Gcse maths and doing maths Alevel said it's 8 give or take the 0.17

Ignore me! 64x0.2 = 12.8 so root 13?

Yes I think she got a bit confused here- so
√12 if its multiplication sign as seems to be indicated by the next question??

My son says the answer is 7.8 or -8.2. Doing gcse this year eek. I haven’t a clue by the way 🤣

Square root of 63.5 - answer < (less than) or >(more than) 0.17

sq root is 7.968, allowing for up to .17 more or less =8

Yes root 12 would work if she's estimated to 60x0.2=12

And if the symbol means x !

Ah that makes sense- so its asking for the square root of 63.5 with 0.17 degree of accuracy, logical answer is 8?

But doesn't explain the second one where she has multiplied them together and got 3 marks?

I don't remember our maths at GCSE being this hard!

It should be multiply in both questions.

Look at the June 2019 higher maths paper edexcel, questions 8 and 9, as it's printed properly there - if your computer doesn't display it correctly, check another screen, because it is definitely multiply.

The first one is actually asking for an estimate of the square root of 63.5 x 101.7, which approximates to the square root of 64x100, ie. 8x10, or 80.

the second is 3 and 1/2 multiplied by 1 and 3/5, or 7/2 x 8/5 = 28/5 = 5 and 3/5

I thought that looked a familiar question

Estimate
sqrt of (63.7 x 101.7)

So you can use sqrt 64 x sqrt100 = 8 x 10 =80

So this has been completely mist typed? Thank you for this paper-because the question in it is √63.5x101.7 but the subsequent Qs are identical...how on earth is she meant to decode these in an exam!

Just want to say a massive thank you to everyone who took time to have a look at this-trying my hardest to help her!

I suspect someone typed the paper out at some point but used some kind of font that wasn't recognised - or perhaps they tried to print a version from online, and again, the font or layout wasn't recognised by the priinter, and it printed incorrectly. And they've been photocopying it ever since!

The exam will be printed properly.

Not what you’re asking but what is the actual point of this kind of maths equation?

Like, so few jobs will ever have a need for it, I’m so glad I don’t have to do GCSE’s now!

I would love to see what answer the teacher suggests to the question posted as printed in the OP

Ah that makes sense, root (64x100) so 8x10 = 80
I hope she hasn't got too frustrated with it!

I am going to ask if the teacher can show their working for it on my daughter's paper, since they have not gone through it or shown the answer. She is trying to get an 8 or 9- and got a very very poor mark in this exam. I suspect we may find further typos as we go through the paper

An actual exam paper should be printed correctly!

I expect her confidence was knocked by the format and she then felt less able to risk take in the harder questions. I hope she feels better about her mark now she knows about the typos

Yes it was but now I have shown her the actual question she feels much better

Thank you so much everyone

80.8 without the typo
