So today's editorial office. "Site" It offers readers an IQ test of a specialist from the Massachusetts Institute of Technology. There are only 3 simple questions that rarely get 3 correct answers.





This test is not new, because a professor at the Massachusetts Institute of Technology Shane Frederick developed it about 15 years ago. During this time, more than 3 thousand people passed the test, and the mathematician was more than once convinced of its effectiveness.

Even Yale and Harvard students They made mistakes by giving the wrong answers. From all interviewed Only 17% of people They dealt with the following questions. You try to do it, too.





Questions

1. The bat and the ball together cost $1 and 10 cents, while the bat is worth exactly $1 more than the ball. How much does the ball cost?
2. If 5 machines produce 5 products in 5 minutes, how long will it take 100 machines to produce 100?
3. The lake is rapidly overgrown with lilies: every day the number of plants doubles. It is estimated that in 36 days the lilies will completely cover the lake. How many days would it take lilies to cover half of the lake?
   
   
   
   

Although the tasks are simple, they are simple and involve the same simple answers. brain It is designed in such a way that in the first place offers the wrong option. Can you handle all the tasks correctly? Below are the correct answers with explanations.





Answers.

1. The most common answer is that the ball costs 10 cents. But that's the wrong answer, because then the bat will cost $1, which is 90 cents more than the ball. And the condition indicates the difference in price is 1 dollar. For the solution, you can use the school equations by taking the unknown (cost of the ball) for X. In this case: ball + bat = X + X + 1 $ = 1.1 $.
   
   Based on this, 2X = $0.1, which means that one ball costs only $0.05. Then the price of the bit will be $ 1.05. Although you can try to find the answer by simply selecting numbers in your mind.
   
   
   
   
   
   
2. The answer is usually 100 minutes. But it's not. After all, if 5 machines need 5 minutes to create 5 products, then one machine spends 5 minutes on the production of one product. Therefore, having 100 machines at once, each of which spends the same 5 minutes on the product, it will take only 5 minutes to produce 100 units of products.
3. The most common version is about 18 days. But it's a tricky trick again. After all, the number of lilies increases exponentially with a denominator of 2, and therefore if on the 36th day the lake is filled by 100%, then on the previous day (35th) there were 2 times less plants. It takes plants 35 days to capture exactly half of the lake.
