15 or more days are counted as one month.

• The months are also transformed into years. For example, 6 years and 4 months Mean

years = = years.

intelligence development. If a child is able to perform such mental activities properly which
are found suitable for his chronological age, it is considered that his mental age is equal to his
chronological age.

person. To remove the decimal point from this ratio, it is multiplied by 100. Thus,

• Intelligence quotient =

I.Q. =
