Answer :
To calculate Victor's IQ, we use the formula IQ = mental age / chronological age * 100. With a mental age of 12 and a chronological age of 12, Victor's IQ calculation results in 100, indicating that his mental capacity is in line with his chronological age.
The question concerns determining Victor's IQ based on his mental and chronological ages. To calculate IQ, the formula IQ = mental age / chronological age * 100 is used.
As Victor is 12 years old and has a mental age of 12, we apply the formula as follows:
IQ = mental age / chronological age* 100
IQ = 12 / 12* 100
IQ = 1 *100
IQ = 100
Therefore, Victor's IQ is 100, which is considered average, as it indicates that Victor's mental age corresponds exactly to his chronological age, similar to the examples where a 10-year-old child who does as well as the average 10-year-old child also has an IQ of 100.
