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).

Developmental delay is calculated with the IQ (Intellectual Quotient) level of the child. IQ = Mental Age/Chronological Age * 100 Mental Age is calculated against a set of checkpoints of the Child Development Milestone chart For Example IQ = 0.3/0.8 * 100 (in terms of months) = 35% approx.; that means the infant is 8 months old but the mental age is only as of a 3 months old baby, so there is a delay of 5 months of cognitive development Average expected IQ level is 70% and above
All I can say is that it is likely to be a low IQ, because with the IQ system it is a probability distribution with a mean of 100. Therefore anything below 100 is less than average, and 100 is a hard age to reach to say the least. However, there isn't a set proportionality with age and IQ so it cannot really be determined after that.
anywhere over the IQ of 100 because the IQ of a 12 yr old is 150 but it is also differed by mental age divided by chronological age i hope this helped
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.
It depends on how your chronological age is measured and scored. Often that is described as your intelligence quotient (or IQ).
Her IQ can be calculated using the formula: (mental age / chronological age) * 100. In this case, her IQ would be (20 / 10) * 100 = 200.

The first effective tests of mental faculties were developed by Alfred Binet and Theodore Simon in 1905 with the creation of the Binet-Simon intelligence scale. This test was designed to measure a child's mental age in relation to their chronological age and is considered the foundation for modern intelligence testing.
The world's first standardized intelligence test was developed by Alfred Binet and his colleague Theodore Simon in France in 1905. This test was later refined and translated into English by Lewis Terman in the United States, leading to the creation of the Stanford-Binet Intelligence Scale.

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.

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.
He/she is a total child whose physical and mental development coincides with his/her age.
