One activity that many of our members enjoy is puzzling! You can test yourself for fun with our brainteasers. Our quizzes and conundrums are updated regularly, so do check back on the page for the latest content, and if you get really good at them, why not find out what your IQ is by booking a Mensa Supervised IQ Test?

3/7/25 – Nora’s Novel

Nora wrote her first novel.

The ending was 80 pages long.

The start was as long as the ending plus one fifth the length of the middle.

The middle contained the same number of pages as the start and ending combined.

How many pages were there in the complete novel?

E = 80, S = E + 1/5M, M = S + E

M = 2E + 1/5M,

M = 200, S = 120
