Question

Two students have same IQ. Which of the following cannot be correct ?

• A. Both can have same chronological age and mental age
• B. Both can have different chronological age and mental age
• C. One is elder than the other
• D. Both can have same chronological age but different mental age

Answer 1

Answer:

D. Both can have same chronological age but different mental age

• IQ (Intelligence Quotient) is calculated by dividing Mental Age (MA) by Chronological Age (CA) and multiplying by 100:

IQ = (MA / CA) x 100

• If two students have the same IQ, it means that the ratio of their Mental Age to Chronological Age is the same.

• Therefore, if they have the same chronological age, they must also have the same mental age. Having different mental ages would result in different IQ scores.
