Calculate the Intelligence Quotient of an individual who is 12 years old and has the mental age of a 12-years old.

100

The correct answer is Option (1) → 100

The formula for Intelligence Quotient (IQ) is: IQ= [Mental Age / Chronological Age] ×100

Here:

• Mental Age = 12 years

• Chronological Age = 12 years

IQ = [12/ 12] * 100 = 100
