1. Children: 20% + teenagers 25%
Seniors= 17%
45/17= 2.65~

2. 540 people = difference of (23%+25%+20%= 68%)- 32% = 36%
36% is 540 people then total = 540/36%= 1500

Official Explanation

1. The census indicates that______________times as many residents were children or teenagers as were seniors.

According to the graph, 45% of the residents were children or teenagers and 17% were seniors. Therefore there were 45/17≈2.65 times as many residents who were children or teenagers than were seniors.

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______________.

According to the graph, at the time of the census, 68% of residents were aged 0–39 and 32% were aged 40 or greater. If P represents the total population of Town Y, then $$540 = (0.68)P − (0.32)P.$$ Therefore, 540 = 0.36P, so P$$=\frac{540}{0.36}=1,500.$$

Since its mentioned as The census indicates that times as many residents were children "or" teenagers as were seniors.
