NFER MATHS - PAPER 11B - Q31 - IMPOSSIBLE!
Just looking at this paper I spotted a diagram in question 31 on NFER Paper 11B asking a child to calculate the area of a parallelogram.
It gives the lengths of two of the sides as 5 cm and 3 cm. Hence the parallelogram has sides 5 cm, 3 cm, 5 cm and 3 cm. It then proceeds to show that 1 cm from one of the apex the perpendicular height is 2.7 cm.
Either NFER have it wrong or Pythagoras got it wrong!
The diagram is asking you to accept:
3 squared = 1 squared + 2.7 squared
I have checked this question with other mathematicians and the diagram is WRONG!. If NFER cannot get their questions right what hope do we have? How do you justify to your child that although NFER have got this question wrong they still set the exams?

NFER ERRORS
Maths is not the only area where NFER have made errors. I came across a few in non-verbal reasoning whcih burdened me for weeks. In the event I submitted the question to a tutor who cofirmed it was an error by NFER.
Problem is NFER don't have customer service section that can verify whether there is mis print or mistake with any questions and so some of us end up pulling our hair out for weeks on end ... I think NFER should have a 24/7 helpline for us 11 plus parents!

Nfer misprints
Hi
I very much interested in the comments regards misprints found in the NFER papers
I think I may be in a similiar situation as I have been doing the NVR papers with my daughter and came across some answers that I thought were suspects. I have spent quite a time puzzling over their answers and still not sure.
I just wondered if you could let me know what NVR paper/Q the misprints are.?
I intend to take the matter up with NFER .

Hi Guest 473
I am inclined to agree with you that what I thought was a misprint was infact the correct answer. I am referring to the NVR paper that I had spent ages figuring out the correct answer.
I did get in touch with NFER and they claimed that to the best of their knowledge there were no misprints.

The diagram is misleading but NFER have covered themselves by not labelling exactly where the 1cm is measured to and at the same time not explicitly stating 2.7cm is the perpendicular height. The 1cm is in effect "information overload" to confuse anyone not sure which measurements to use to obtain the correct answer.
To be fair, the majority of children (10 or 11 year olds) taking this type of tests would have only been taught the basics of mathematics and have around 1 minute to workout the answer and hopefully it's the correct one too.

Nfer Maths Q 31 paper 11B
Area of a parallelogram = Base x perpendicular height, regardless of the drawing this should be a simple case of knowing your formulas, not questioning the drawings accuracy, surely ?
