A. 100
B. 120
C. 50
D. 140
Answer is = B
You are correct! The IQ of a student having a mental age of twelve years and a physical age of ten years would be:
B. 120
Here’s how to calculate it using the IQ formula:
IQ = (Mental Age / Chronological Age) x 100
- In this case, the student’s mental age (MA) is 12 years and their chronological age (CA) is 10 years.
- Plugging these values into the formula:
IQ = (12 years / 10 years) x 100 = 1.2 x 100 = 120
Therefore, the student’s IQ score would be 120, indicating above-average intelligence relative to their chronological age. Their mental age is two years higher than their chronological age.
