Question

if a child has mental age of 5 years and chronological age of 4 years than what will be the IQ child?​

Answer 1

If the 10-year-old had a mental age of 8, the child's IQ would be 8/10 × 100, or 80. Based on this calculation, a score of 100—where the mental age equals the chronological age—would be average. Few tests continue to involve the computation of mental ages. See also Lewis Terman; Alfred Binet.

Answer 2

The IQ of child is 125.

Step-by-step explanation:

Consider the provided information.

It is given that the mental age of the child is 5 years and the chronological age is 4 year.

To calculate the IQ level of the child use the formula:

$IQ = \frac{\text{Mental age}}{\text{Chronological age}} \times 100$

Substitute the respective values in the above formula.

$IQ = \frac{5}{4} \times 100$

$IQ =1.25\times 100$

$IQ =125$

Hence, the IQ of child is 125.
