If William's mental age is equal to his chronological age, then his IQ would be exactly average, which is 100. It is said that a person's IQ is calculated by dividing his or her mental age by his or her chronological age and then multiplying it by 100. Therefore, 11/11 * 100 = 100, which is the average IQ score.
