It doesn’t have a formula

Detailed explanation-1: -The IQ was originally computed as the ratio of a person’s mental age to his chronological (physical) age, multiplied by 100. Thus, if a child of 10 had a mental age of 12 (that is, performed on the test at the level of an average 12-year-old), then the child was assigned an IQ of (12/10) X 100, or 120.
Detailed explanation-2: -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-3: -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-4: -An individual’s mental age is then divided by his chronological age and multiplied by 100, yielding an intelligence quotient (IQ). Thus, a subject whose mental and chronological ages are identical has an IQ of 100, or average intelligence.
Detailed explanation-5: -Intelligence Quotient (IQ) is the score you get on an intelligence test. Originally, it was a quotient (a ratio): IQ= MA/CA x 100 [MA is mental age, CA is chronological age]. Today, scores are calibrated against norms of actual population scores.
