The shortest IQ test, in just three questions
There are many IQ tests that aim to exercise your mind, most of them very complex. However, this one only has three questions. The test is as short as it is effective because its ultimate goal is to analyze people’s ability to penetrate deeply into the details of a more difficult problem than it seems at first glance. Here are the three test questions:

- A ball and racket together cost 11 euros. The racket costs 1 euro more than the ball. How much does the balloon alone cost in this case?
- We have 5 machines that take 5 minutes to produce 5 items, how long will it take 100 machines to produce 100 items?
- On a lake, there is an area with water lilies. Every day, this area doubles in size. If it takes them 48 days to fill the whole lake, how long will it take for the water lilies to cover half the lake?
Here are the correct answers:
- The balloon costs 5 euros.
- It would take 100 machines 5 minutes to produce 100 objects.
- Water lilies would cover half the lake in 47 days.
The intelligence test was applied to 3,500 people. Of these, 33% got all three answers wrong, and 83% of respondents got at least one question wrong, and 48% of students who took the survey answered all three questions.
