Following on (finally) from the previous maths-related post, I saw this in an Edexcel maths exam paper:

Question (a) is “How did most of the students travel to school?” My answer was “by vehicle”, since car+cycle+bus = 55%. But the maths teacher told me the correct answer is “walk” since it’s the largest piece of pie. Apparently, maths teachers speak a different language from the rest of us.
