Answer 2

Answer:

Explanation:

If we say the child has an IQ of 100, it means The mental age of the child is equal to his actual age .

IQ was first calculated by multiplying the ratio of mental age to chronological (physical) age by $100$ . Thus, if a $10$-year-old child had a mental age of $12$ (that is, performed at the level of a typical $12$-year-old on the exam), the child was given an IQ of $\frac{12}{10}\times 100$  or $120$.

The final answer is the mental age of the child is equal to his actual age .
