Detailed explanation-1: -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-2: -The formula for the calculation of the Intelligence Quotient (IQ) is MA/CA x 100. The shorthand for intelligence quotient is IQ. The intelligence quotient (IQ) is a numerical indicator of a person’s intelligence.
Detailed explanation-3: -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-4: -IQ of a person is given by the formula IQ = MACA × 100 where MA is mental age and CA is chronological age. If 80 < IQ < 140 for a group 12 years old children, find the range of their mental age.
