Puzzles

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?

10/12/24 – Elf Centre

Three Christmas Elves Eric, Edwin and Elba wrap presents at different rates.

Eric can wrap 15 presents in an hour.

Edwin can wrap 3 presents in 20 mins.

Elba can wrap 4 presents in 15 mins.

How long will it take them to wrap 90 presents between them (assuming they continue to work at a constant rate)?
