Correct Answer: 30
Solution :
The difference between the number of people in the age groups (46–55) and (16–25) = 0.975 million
The difference corresponds to the difference in their percentages = 18.25% – 15.00% = 3.25% of the total population
⇒ 3.25% × Total population = 0.975 million
$\therefore$ Total population = $\frac{0.975}{3.25\%}$ = 30 million
Hence, the correct answer is 30.
