Correct Answer - Option 2 : 12
IQ or Intelligence Quotient is the measure of a child's ability to reason and solve problems. It is the test to measure human intelligence.
- An individual’s Intelligence Quotient (IQ) is determined by multiplying the quotient of his/her mental age and chronological age by 100. i.e.
\(IQ=\frac{Mental Age}{Chronological Age}\times 100\)
MentalAgeChronological
∴ Mental Age (MA) = [Intelligence Quotient (IQ) × Chronological Age (CA)]/100
Given, IQ = 75, CA = 16, MA = ?
∴ MA = (75 × 16)/100
= 1200/100
= 12 years
