Answer 2

The correct option is (3) 12 years.

Step-by-step explanation:

Consider the provided information.

Ramesh and Ankit have the same IQ of 120.

Ankit is 12 yr old, Ramesh is two years younger than Ankit.

That means Ramesh is 12-2=10 year old.

The formula to calculate IQ level is:

IQ = Mental age ÷ Physical age × 100

Substitute the respective values in the above formula.

$120 = \frac{\text{Mental age}}{10}\times100$

$120 ={\text{Mental age}\times10$

${\text{Mental age}=\frac{120}{10}$

${\text{Mental age}=12$

Hence, the mental age of  Ramesh is 12 years.

Therefore the correct option is (3) 12 years.
