    Question

    A person’s chronological age is 20 years and mental age is 16 years. What would be his IQ?

    A.

    120

    B.

    100

    C.

    80

    D.

    More than one of the above

    E.

    None of the above

    Correct option is C

    IQ (Intelligence Quotient) is calculated using the formula:

    IQ = ( Mental Age /Chronological Age ) × 100

    Here, the chronological age is 20 years, and the mental age is 16 years.

    Substituting the values into the formula: I Q = ( 16/20 ) × 100 = 0.8 × 100 = 80
