Answer 2

Answer:

The mental age of Sohan is 9 years.

Explanation:

Given Intelligent Quotient ( IQ) = 75 .

Intelligent Quotient : It is the ability of the person to solve or resolve the problems. It is a quantitative property.

• It reflects how well you did on a particular test compared to others your age.
• Tests vary, but many tests have an average IQ of 100, with 68% of scores between 85 and 115.

Chronological age of the person is 12 years

Chronological age : It is the actual age of the person.

let mental age be A.

we know that

IQ = (Mental Age /Chronological Age)×100

So, 75 =( A / 12 ) × 100

A = 75× 12 /100

A = 9

So the mental age of the sohan is 9 years.
