(i) Aabha is a genius girl. Her chronological age is 8 years and her mental age is 14 years. Find out her I.Q. 

(ii) Mayur has learning disabilities. His chronological age is 8 years and his mental age is 6 years. Find out his I.Q.

Answer 1

(i) In case of Aabha – Mental Age (MA) = 14 years 

Chronological Age (CA) = 8 years, IQ = ?

IQ = \(\cfrac{MA}{CA}\) x 100 = \(\cfrac{14}{10}\) x 100 = 175

IQ = 175

(ii) In case of Mayur – Mental Age (MA) = 6 years. 

Chronological Age (CA) = 8 years, IQ = ?

MA 6

IQ = \(\cfrac{MA}{CA}\) x 100 = \(\cfrac{6}{10}\) x 100 = 75

IQ = 75.
