Explanation Given that, the chronological age of the children is 12 and the IQ level varies from 80 to 140. Note that, the IQ level is obtained by the formula MA CA × 100 . The range of the mental ages of the 12 year old children whose IQ level varies from 80 to 140 is given by, 80 < IQ level < 140 80 < MA CA × 100 < 140 80 < MA 12 × 100 < 140 80
