Maths was always my strong suit so this was an easy 7 - without a calculator too :)
(Hint for WyeDyed on doing the "How far north" question without a calculator: 72 degrees is greater than 60 degrees, so cos(72) is less than a half - only one of the answers was less than half the hypotenuse, so it had to be that one. It would have been trickier without a calculator if the possible answers were closer together, e.g. 1.04, 1.05, 1.06).

Yes indeed, jtp, so much care is needed to make no mistakes. Rather like computer programming, a single figure out of position, or a sign error, or decimal points, etc., all of thees can carry over for so long and never be noticed until too late, and then you have to go all back again and trace it. Horrible. In A-Levels I managed to get A's in all subjects but missed out on 100% on most/ all papers because of those sorts of silly errors.
What amazed me was that these were apparently GCSE questions.
I did more difficult "sums" when I took my eleven-plus. For example, add 17.5% to one number and calculate the difference between the answer and another number! Is 0.25% equal to a quarter !!
I got all seven correct and did them all in my head bar the one which needed to find the Cosine of 72 degrees. If this is stuff that students of 16 years old, following eleven years of education, are tested on then I'm not surprised that the nation's bosses believe that many youngsters are ill-equipped for the workplace.
