Detailed explanation-1: -Chronological age is a measure of an individual’s age based on the day, month and year the individual was born. Mental age is different from chronological age in that mental age is based on your intellectual development, not your date of birth.
Detailed explanation-2: -IQ was originally computed by taking the ratio of mental age to chronological (physical) age and multiplying by 100. Thus, if a 10-year-old child had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), the child was assigned an IQ of 12/10 × 100, or 120.
Detailed explanation-3: -Hence, we conclude that if a student’s chronological age is 4 years and the mental age is 5 years, his I.Q. will be 125.
