Solution

Given, the formula for the IQ of a person is,

IQ= MA CA ×100

Where, MA is the mental age and CA is the chronological age.

Since, the current age group of children is 12years old i.e. CA=12.

IQ= MA 12 ×100

Substitute the value of IQ in 80≤IQ≤140.

80≤IQ≤140 80≤ MA 12 ×100≤140 80×12 100 ≤MA≤ 140×12 100 9.6≤MA≤16.8

Thus, the range of mental age for children of 12 years old is 9.6≤MA≤16.8.
