Chronological age (as it pertains to humans) is the actual age of a person from the moment of birth to any point in time as long as that person is alive. It is the actual time span. Thus a person could be 5 years old, 11 years 10 months 2 days old...etc.
The mental development of a person is reflected in the mental age of a person. The mental age can be quite different from the chronological age. There are accepted mental development standards for an average person based on his/her chronological age. But these standards vary based on many factors, some of which are
1) Environment in which the person grows.
2) Things and situations that the person is exposed to
3) Home and societal environment
4) Stability of a society
5) Absence of war and destruction
6) Disease including mental
7) Lack of nutrition
8) Stability of the family
9) Inborn gift or lack of it
and many more
Thus we may encounter an eight year old doing and understanding college level math and science (a gift) or a 50 year old who can hardly count one through 10. Thus even though there is a linear relationship between chronological age and mental age for the average population, it can vary from person to person due to one or more of the above reasons and others.
IQ = mental age / chronological age x 100
It depends on how your chronological age is measured and scored. Often that is described as your intelligence quotient (or IQ).

IQ = mental age / chronological age x 100
Your IQ is calculated by dividing your mental age over your chronological age multiplied by 100.You mental age is simply how you behave or your personality and your chronological age is how old you are at the moment.

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).
No, 68 percent of the world's population has an IQ of between 90 and 110, an IQ of 120 means that about 95 percent of the world's population is below that point in IQ. An IQ of 100 is average.

Chronological age is the years you have been alive and health age is the physical age your body is. If you are obese and not in shape for instance or if you smoke a lot, your health age is probably a lot older then your chronological age.
Basically it means how old your character is, for example, if a someone who was 20 had a mental age of 6 they would probably be acting like a 6 year old and have similar characteristics. Mental age is a controversial concept in psychometrics. It is an intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. Hope this helps :D
Alfred Binet and Theodore Simon created the first standardized intelligence test in 1916. Francis Galton made the first attempt to create such a test before them, but was unsuccessful in creating a test because he could find no correlation between physical development and mental development. Binet and Simon created a test that would require participants to give answers that would relate to their "mental age", meaning that the more advanced the question, the more likely an older participant would be able to answer correctly. This mental age reflected the mental ability of a child. If a child had a higher mental age than his/her chronological age, (for example, an 11 year old scores a mental age of 13) then the child was considered gifted or mentally advanced. If a child had a lower mental score than his/her chronological age, (for example, an 11 year old scores a mental age of 10) then the child was seen as underdeveloped or mentally retarded.
