If the mental age of a 10 year old boy is 12, then what is his IQ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 120
The formula for Intelligence Quotient (IQ) is: IQ= [Mental Age / Chronological Age] ×100

Mental Age = 12 years
-
Chronological Age = 10 years
IQ = [12/ 10] * 100 = 120
