To calculate IQ, take a person's mental age, divide it by chronological age, and then multiply that number by 100. For example, if a person has a mental age of 12 but is 10 years old, then you'd divide 12 by 10, and multiply that number by 100, which would result in an IQ of 120.
The golden ratio, also known as the golden number, golden proportion, or the divine proportion, is a ratio between two numbers that equals approximately 1.618. Usually written as the Greek letter phi, it is strongly associated with the Fibonacci sequence, a series of numbers wherein each number is added to the last.
Multiply 20 by 45 and divide both sides by 100. Hence, 20% of 45 is 9.
The answer is the same. 25% of 80 is 20.

Since women carry two X chromosomes while men carry only one, scientists say there is a higher chance that intelligence-related genes come from the mother. This does not mean fathers do not contribute to intelligence, but it suggests the maternal line may have more influence at the genetic level.
Processing speed and executive function can improve with regular use of apps that present increasingly difficult logic puzzles and math problems. Physical activity, adequate sleep, and even mindfulness training have been linked to sharper mental performance and better IQ test outcomes.
