Someone with an IQ of 40-70 is dumb. Someone with an IQ of 1-20 has the intelligence of a starfish.
IQ is not strongly associated with age. An IQ of 56 represents mental retardation, but nothing about the person's age.
Age and gender doesn't affect your IQ. The IQ is kind of like a measure of your mental age. I know when I took an IQ test I got an 130 and that made my mental age 16 (at an age of 13). An IQ over 140 means someone is a genius, while the average is between 90 and 110. If it's under 70, just hope you're as lucky as forest gump.
If the boy's chronological age and mental age are equal, his IQ would be assumed to be 100. (Using chronological age x IQ/100 as the template).
The IQ would be 100.

IQ = mental age / chronological age x 100

The average IQ of 100 is set by design to represent the midpoint of the IQ scale, with the majority of the population falling within one standard deviation above or below this value. This value provides a standardized reference point for comparing individuals' intelligence relative to the population.
The IQ would be 100.

a 10-year-old with a mental age of 10, therefore, has an IQ score of 100. However, if the mental score is lower than the age, it drags the IQ score down. So, if the 10-year-old's mental age is 8, their score would only be 80
The word "moron", which is now considered to be outdated and cruel, was a term used in the psychological community to describe someone who had an IQ of 51-70 (or a mental age of 8-12). This is now called "mild mental retardation".
Her IQ can be calculated using the formula: (mental age / chronological age) * 100. In this case, her IQ would be (20 / 10) * 100 = 200.
IQ is traditionally the ratio of mental age to physical age multiplied by 100. At the extremes, it's largely meaningless - an IQ of 1 would mean a 100 year old person with a mental age of 1. The average IQ (Intelligence Quotient) is between 90 - 110. So for one to have an IQ of 1 would be highly improbable.
The average IQ for a 13-year-old is around 100, which is the same as the average IQ for the general population. IQ scores are standardized by age, so a score of 100 is considered average for all age groups.
