Detailed explanation-1: -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.
Detailed explanation-2: -mental age, intelligence test score, expressed as the chronological age for which a given level of performance is average or typical. An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ).
Detailed explanation-3: -The IQ of person is given by the formula, IQ=mc×100, where m is the mental age and c is the chromological age. If 80≤IQ≤140 for a group of 12-year children, find the range of their mental age.
Detailed explanation-4: -Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.
