GCSE students took their Edexcel maths exam this morning, and it seems fair to say that it was a bit of a stinker.
Using the hashtag #EdexcelMaths, they are mocking the paper on Twitter.
One question in particular, about Hannah and her sweets, was not exactly popular.
There was also a question about a guy called Karl, who apparently sucks at raising money for charity.
There was one about a girl called Raksha and her poor timekeeping.
One about someone called Mary, who wanted a conservatory.
And one about someone called Jane and some cheese, which is making people pretty angry.
But at least they now know where to buy their plants.
It had all started off so perfectly.
Oh well. John's always around to help.
Can you solve the question about Hannah's sweets that's left teenagers across the country stumped?
Here's the question:
Hannah has 6 orange sweets and some yellow sweets.
Overall, she has n sweets.
The probability of her taking 2 orange sweets is 1/3.
Prove that: n^2-n-90=0
