A question that appeared in a further maths exam has prompted debate over whether it was too hard to answer.

The multiple-choice poser was given to 17- and 18-year-old Year 12 students in Australia and asked them to find the degree of angle between two 50 cent coins with 12 sides each.

Students had a choice of answers: 12, 30, 36, 60 or 72 degrees. The answer is revealed in the box below, but many took to social media to complain the question was simply too difficult.

“That exam wasn't there to test us, it was to trick, no one could have prepared for that,” one student wrote.

Another said: “The 50 cent coin question makes no sense to me as it asked us to find the angle, but it gave us no other angles or lengths to enter in the formulas so there was simply no way about it.”

However, others claimed the question was too easy for a further maths exam.

A teacher, Darren Adams wrote: “And this stumped VCE students? Gimme a break! My Year 5s could have worked it out.”

Pothiraju Seetharam added: “It is easy. Overthinking did them in.”
