1)B, Children=20%
Teens=25% and seniors=17%
So ratio is 25+20/17= 45/17=2.65
2)A,Total % of people from 0-39= 20+25+23= 68% of total population
And rest is 32% of total population,Now given difference is 540= (68-32)of total population
Total population = 540*100/36=1500

1. The census indicates that______________times as many residents were children or teenagers as were seniors.
Let the total population of Town Y be x.
Senior citizens make : 17% of x.
Children or Teenagers make: 45% of x.
Now we are asked: 45% of x = k17% of x.
k = 2.647 => ~ 2.65
Answer B.
2. If, at the time of the census, there were 540 more people aged 0–39 than people aged 40 or greater, then the population of Town Y at the time of the census was______________.

people aged 40 or greater make up: 32% of x.
Now, Given: 68% of x = 32% of x + 540
=> (36/100)x = 540 => x = 54000/36 = 1500.
