With just 3 questions this is the world’s shortest IQ test (and a third of people get all 3 wrong)
Everyone loves doing an IQ test. If only they weren’t so long, right?
Help is at hand with something called the Cognitive Reflection Test (CRT) which is dubbed the world’s shortest IQ test because it has only 3 questions, which suits our IQ down to the ground, frankly.
But 80% of people get at least one question wrong and a third of people get ALL 3 wrong.
How do you do?
1.
A bat and a ball cost £1.10 in total. The bat costs £1.00 more than the ball. How much does the ball cost?
2.
If it takes five machines five minutes to make five widgets, how long would it take 100 machines to make 100 widgets?
3.
In a lake, there is a patch of lily pads. Every day, the patch doubles in size. If it takes 48 days for the patch to cover the entire lake, how long would it take for the patch to cover half of the lake?
Don’t scroll down unless you think you know the answer (or you can’t be arsed to try, obviously).
We said DON’T SCROLL DOWN.
Just in case you need some inspiration.
Okay, okay, here are the answers (with some typical wrong answers in brackets).
1.
5 cents (not 10)
2.
5 minutes (not 100)
3.
47 days (not 24)

We’re off for a lie down.
