In using the intelligence quotient (IQ) to compare the two boys, we divide their mental age by their chronological age and multiply by 100 to get their IQ score. Walter's IQ score would be 80 (8/10 x 100), and Alfred's IQ score would be 83.33 (10/12 x 100). Therefore, Alfred would be considered more intelligent than Walter.
