Rather than carrying out a long test to determine your level of intelligence, you can now try answering just three questions to reveal your smarts.
Sound simple enough? Well, the questions are a lot more difficult than they may seem at first glance, and understanding their depth is actually part of the assessment.

The Cognitive Reflection Test was originally published in the Journal of Economic Perspectives in 2005, and is the world's shortest IQ test, the Mail Online reports.

Take the quick test below to find out if you have above average intelligence…

THE IQ TEST

1) A chalk and a chalkboard cost #5.50 in total (five naira fifty kobo). The chalkboard costs #5.00 more than the chalk. How much does the chalk cost?

2) If it takes five machines five minutes to make five rubber hangers, how long would it take 100 machines to make 100 rubber hangers?

3) In a football field, there is a patch of Ryegrass. Every day, the patch doubles in size. If it take 32 days for the patch to cover the whole field, how long would it take for the patch to cover half of the field?
