Three questions prepared by Professor Frederick, also known as the world’s shortest IQ test, were prepared to measure your intelligence. However, only 13 percent of those who take this test and answer the questions are fully successful. The remaining part fails the test by giving wrong answers to the questions in the test. So, are the questions in the world’s shortest IQ test really that hard? Let’s take a look at the details of the news together.
The world’s shortest IQ test questions!
The world’s shortest IQ test, first prepared by Professor Frederick in 2005, is still in use today. Also called the Cognitive Reflection Test, this test consists of only three questions.
- A stick and ball costs $1.10. If the stick costs $1.00 more than the ball, how much will the ball cost?
- If 5 machines produce 5 products in 5 minutes, how long will it take 100 machines to produce 100 products?
- In a lake covered with water lilies, the flowers are growing to double their size with each passing day. If it takes 48 days for lotus flowers to cover the entire lake, how long will it take to cover half the lake?

World’s shortest IQ test answers
1. While many people think the answer is 10 pennies, this answer is not correct. The correct answer to the first question is as follows:
If we call the stick x and the stick is $1 more than the ball, it becomes x+1. Therefore, the cost of the stick and ball will be 2x+1. Thanks to the information obtained from the question with the result obtained here, it remains to take action to reach the answer.
2x+1= $1.10
2x= $1.10 – 1
2x= 0.10 penny
x= 0.05 penny
2. Although many people think that the answer is 100, this is not true. If 5 machines can produce 5 pieces of a product that takes 5 minutes to produce, then 100 machines can produce 100 products in proportion. simultaneous can produce in 5 minutes by working as
3. Many people find the answer as 24 days by dividing 48 by two because they said half. But this is not a correct answer either. ‘Cause here to find the answer, let the flowers grow ratio should be looked at. Whatever the answer, it was half full the day before it was fully covered with flowers. Therefore, the answer is 48-1=47.
