IQ above 180 only used once, can you

3 times 2 (6, 6) the first time, 6 6 in a group, the second time, the light 3 in a group, the third time, the light one in two bags to weigh, if balanced, the other bag is false, if unbalanced, the light bag is false so it is three times.

Number the 12 bags, from 1 to 12, take out the same number of gold coins from the bags and weigh them on the scale. In this way, a total of 78 gold coins were withdrawn. If all 78 are true, then it should be 780 grams, of course, it can't all be true.

So a few grams is a few bags that are fake.

This should work

1 time. Take 1 gold coin in the first one, 2 gold coins in the second one, and so on, and then weigh it. If it is true, it should weigh 780 grams, and a few grams less will be in which bag. If it is one gram less, it is in bag No. 1.

Hehe, this is what our Olympiad teacher taught. Elementary 5 Question 0 Take 1 gold coin from the 1st bag, 2 from the 2nd bag, 3 from the 3rd bag, and 4 ...... from the 4th

If it was all true, it should be 780 grams.

The actual 1 gram less in the 1st bag is fake, 2 grams in the 2nd bag is fake, 3 grams in the 3rd, 4 grams in the 4th ......

1 time. Give the bag a number, 0-11, and take the same number of gold coins from the bag. Total weight - 10 * 66 = the bag in which the counterfeit money is located.

At least once!

Up to 11 times!

Upper-middle level.

Different intelligence theories or intelligence scales use different scores to assess IQ, for example, on the Wechsler scale, a normal person's IQ is between 90 and 109; 110 to 119 is the upper middle level; 120 to 139 is an excellent level; A score of 140 or above is a very good level; And 80 to 89 is the lower middle level; 70 to 79 is the critical state level; 69 The following are mental retardations.

Generally speaking, people with higher IQs have stronger learning ability, but there is not necessarily a complete positive correlation between the two. Because IQ also includes social adaptability.

Difference Between IQ and EQ.

First, IQ and EQ reflect two different psychological qualities. IQ mainly reflects a person's cognitive ability, thinking ability, language ability, observation ability, calculation ability, rhythm ability, etc. That is, it mainly expresses the rational capacity of man.

Second, IQ and EQ are formed on different grounds. Although EQ and IQ are both related to genetic factors and environmental factors, their relationship with genetic and environmental factors is different. IQ is much more related to genetic factors than to socio-environmental factors.

Again, IQ and EQ play different roles. The role of IQ is mainly to perceive things better. People with high IQ have good thinking quality, strong learning ability, and deep understanding, and are easy to make outstanding achievements in a certain professional field and become an expert in a certain field.

If we follow the calculation method of dispersion IQ, an IQ of 180 is already multiple standard deviations. I think it's about 1 in 10 million. You can think of it this way, the world's 7 billion people divided by 50 million is probably the number of people in the world who can have a higher IQ than you.

As for whether it is high or not, it depends on what kind of standard you think is high! Anyway, in our opinion, it's very, very high!

Belongs to high intelligence.

The average person's IQ is between 85 and 115, and the average human IQ is 100.

Studies have shown that the highest IQ population in the world is China and the Caribbean, where the average IQ of the region's citizens is 70. After comparing the relationship between economic conditions and IQ in different regions, the researchers believe that the impact of national IQ on economic development accounts for at least 58%. For citizens with an IQ higher than 70, for every 1 point increase in IQ, public service facilities.

Leaders who emerge from groups with high IQs tend to be more competent. Although the main factor that determines IQ is genetics, the objective environment can also greatly affect the development of IQ. In developed countries, IQ per capita can increase by 25 points over a generational period.

The quality of nutritional status has a significant effect on the level of IQ. Even in developed countries, there have been cases where poor nutrition affects IQ.

Note: Most of the intelligence tests developed in the early days were in the form of individual tests. This is the best way to assess mental function alone. At present, there are two main types of personal intelligence tests commonly used in the world:

Stanford-Binet Intelligence Scale and Wexler Intelligence Scale. Both tests are revised in China.

The Wechsler scale can also be used to diagnose a range of mental disorders. Group intelligence tests are mostly selective (or identifial) paper-and-pencil tests, including verbal reasoning, numerical performance, general knowledge and non-verbal reasoning, which are generally applicable to education, industry and military departments, and can quickly obtain objective indicators of the mental function of the subjects.

Special intelligence tests are developed to meet the needs of special populations, such as infant and preschool tests, which focus on developmental issues and tend to emphasize the role of perceptual ability. Intelligence tests for the mentally handicapped and illiterate also fall into this category. Special intelligence tests often include non-verbal items such as drawing figures, image classification, puzzles, building blocks, and solving puzzles.

There is a similar problem on Zhihu, 180, sd=15 is equivalent to 20 million people who can have a greater than or equal IQ, and it is a super genius.

120 is already smarter. But it's not outrageous.

In addition, most IQ test systems are based on the average standard of Western whites, and Chinese have a high IQ relative to whites, and it is said that the average IQ of Chinese, Japanese, and Koreans is about 106 (it is said that the overall IQ of Jews is not high, only about 95, but the average IQ of German Jews is as high as 115, and Einstein, Marx and others belong to the category of German Jews).

Influencing factors

1. Heredity: It is generally said that if the IQ of parents is high, the IQ of children will not be low. This genetic factor is also manifested in blood relations, where the average IQ of a child is 102 if both parents are native; The IQ of children born to parents who married in the next province was 109; Parents are cousins, and there is a noticeable increase in children with low IQ.

2. Breast milk: Breast milk contains a variety of active substances that promote children's intellectual development, especially taurine, which has an important impact on intellectual development, is 10 times higher than cow's milk. According to the survey, children who grow up breastfeeding have an IQ about 3 10 points higher than those who grow up on milk substitutes.

3. Diet: The monotony of the diet leads to the deficiency of certain trace elements, or the amount of diet is too small, and the serious lack of protein and other nutrients will lead to the retardation of IQ development. Excessive intake of heavy metals such as lead and copper can also affect IQ.

4. Weight: Children who weigh more than 20% of normal children will have a low level of vision, hearing, and ability to accept knowledge. This is because the excess fat in obese children enters the brain, which hinders the development of nerve cells and the proliferation of nerve fibers.

5. Environment: Children living in a boring environment, such as abandoned babies, do not have maternal love and good education, and have a low IQ. According to research surveys, the average IQ of such children at the age of 3 is only, and conversely, the average IQ of 3-year-old children in a good environment is.

6. Drugs: Some drugs can affect children's intelligence, such as long-term use of anti-epileptic drugs can make IQ low, when the drug is stopped for a number of years, IQ will be improved.

An IQ above 130 is considered a high-IQ group.

Proportion of high IQ in the population (in thousands):

IQ 120-129, 100 people (10%)IQ 130-139, 25 people (

In 140-149, there were 5 (

With an IQ above 150, there is 1 person (

The proportion of the population with high and low to medium IQs (below 120) is about 87% <>

The age of intelligence can only be expressed in a nutshell, but does not indicate the absolute level of intelligenceIntelligence includes many aspects, such as observation, memory, imagination, analytical judgment, thinking, adaptability, etc. The level of intelligence is usually expressed by the intelligence quotient, which is used to indicate the level of intellectual development.

There is no precise definition of high IQ, generally passing the IQ test, the score greater than how many is high IQ, high IQ is much higher than the average person's IQ.

IQ is not a comprehensive quality of a person. A person's good handwriting does not indicate a high IQ, only a high EQ. Writing can be attributed to both IQ and EQ.

IQ is linked to age and is not equivalent to wisdom.

Of course, the higher the better.

But 110 is enough for the average person, and if you work hard enough, an IQ of 110 is enough to make you a multi-millionaire.

The level of intelligence is expressed in IQ IQ, and the IQ of a normal person is between 90 and 109; 110 to 119 is the upper middle level; 120 to 139 is an excellent level; A score of 140 or above is a very good level; And 80 to 89 is the lower middle level; 70 to 79 is the critical state level; 69 The following are mental retardations.

The limit of normal intelligence is an IQ of 90 110shi
