Show answer & explanation
Correct answer: A
First, look at City A in the table. The percentage of the population in the age group (19–35] is 24%. We are given that this specific group has 31,680 people. To find the total population of City A, we divide the known number by its percentage: Total Population = 31,680 / 0.24 = 132,000. Next, we need to find the number of people in the age group > 60 for City A. The table shows this is 16% of the total population. So, we calculate 16% of 132,000: 132,000 * 0.16 = 21,120.
