This is a classic example of a mental age calculation, where the child's performance on tasks is compared to that of the average performance for their chronological age group. In this case, the 10-year-old is performing at the level of the average 15-year-old, suggesting a mental age of 15. This can be used to calculate the child's IQ score, which is determined by dividing their mental age by their chronological age and multiplying by 100. In this case, the calculation would be (15/10) x 100 = 150, giving an IQ score of 150.
