However all tests and scales use 100 as the IQ of a person of average intelligence. Since the average IQ is said to be 100, hence anything above 100 is considered as above average and below 100 as below average.IQ below 70 is taken as that of mentally challenged person.IQ above 140 is generally considered as that of a genius.We already know that IQ = Mental Age/Chronological Age X 100.
