Quizplus · Accepted Answer

According to the concept of mental age, this eight-year-old child would be performing at the level of an average 10-year-old, thus their mental age is 10. To find the IQ, we divide the mental age by the chronological age and multiply by 100. In this case, (10/8) x 100 = 125, which corresponds to an IQ of 125. Therefore, the correct answer is D - the child has a mental age of 10 and an IQ of 125.
