Question

Jordan is a 10-year-old boy who has a mental age of 8 years. his iq would be ________. 80

Answer 1

I believe the answer is: 80
The formula that commonly used to predict a person's IQ is:

 MA/CA x 100

*MA = Mental age
CA = Chronological Age

So, the the calculation of Jordan's iq would be:

MA/CA x 100

= 8/10  x 100

= 80
