Question

Sally's mental age is 12, but her chronological age is 9. sally's iq is _____.

Answer 1

Answer: 120

Explanation: 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

Answer 2

The correct answer is 133.

A person with an iq score of 133-149 is considered to be a gifted individual. Among the world's large population, only less than five percent of its inhabitants are considered to be a gifted individual. IQ is known as the intelligence quotient.
