Explanation

intelligence Quotient commonly known as IQ refers to the score of standardized test which assesses and measures human intelligence.

The concept of Intelligence Quotient was developed in 1912 by a German psychologist, William Stern.
He also invented the formula to calculate IQ which was MA(mental age) / CA(chronological/biological age) × 100.
A person possessing an IQ of 140 and above is known as genius as they are exceptionally intelligent and possess extreme creativity.
For example, a child’s mental age on an intelligence test comes out to be 6 years while his chronological age is 4 years then his IQ would be 6/4 x 100 = 150
His/her IQ lies in the 140 and above range, it means he/she is genius.
