Did you solve it? Are you smarter than a British 11 year old?

The results from this morning's maths challenge. Stand by to compare your marks!

Earlier today I set you ten questions from the UK Mathematics Trust's Junior Maths Challenge, which was sat by 300,000 11-13 year olds the week before last.

Here are the questions, answers and explanations. I have also included the percentage of children who got it right and the percentage of Guardian readers who did. In one question children did better than Guardian readers (although this was the one with the image that stretched) and in two others the scores were equal. Well done all round, anyway.
