Answers and reasoning. Review before teaching.

1. In a town, there are 344 young dependants (under 15), 160 elderly dependants (65 and over), and 800 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
63
Total dependants = 344 + 160 = 504. Dependency ratio = (504 ÷ 800) × 100 = 63.
2. In a town, there are 31 young dependants (under 15), 9 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
40
Total dependants = 31 + 9 = 40. Dependency ratio = (40 ÷ 100) × 100 = 40.
3. In a town, there are 160 young dependants (under 15), 56 elderly dependants (65 and over), and 400 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
54
Total dependants = 160 + 56 = 216. Dependency ratio = (216 ÷ 400) × 100 = 54.
4. In a town, there are 270 young dependants (under 15), 144 elderly dependants (65 and over), and 600 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
69
Total dependants = 270 + 144 = 414. Dependency ratio = (414 ÷ 600) × 100 = 69.
5. In a town, there are 130 young dependants (under 15), 45 elderly dependants (65 and over), and 500 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
35
Total dependants = 130 + 45 = 175. Dependency ratio = (175 ÷ 500) × 100 = 35.
6. In a town, there are 93 young dependants (under 15), 84 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
59
Total dependants = 93 + 84 = 177. Dependency ratio = (177 ÷ 300) × 100 = 59.
7. In a town, there are 203 young dependants (under 15), 147 elderly dependants (65 and over), and 700 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
50
Total dependants = 203 + 147 = 350. Dependency ratio = (350 ÷ 700) × 100 = 50.
8. In a town, there are 190 young dependants (under 15), 300 elderly dependants (65 and over), and 1000 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
49
Total dependants = 190 + 300 = 490. Dependency ratio = (490 ÷ 1000) × 100 = 49.
9. In a town, there are 52 young dependants (under 15), 46 elderly dependants (65 and over), and 200 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
49
Total dependants = 52 + 46 = 98. Dependency ratio = (98 ÷ 200) × 100 = 49.
10. In a town, there are 90 young dependants (under 15), 84 elderly dependants (65 and over), and 300 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
58
Total dependants = 90 + 84 = 174. Dependency ratio = (174 ÷ 300) × 100 = 58.
11. In a town, there are 23 young dependants (under 15), 9 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
32
Total dependants = 23 + 9 = 32. Dependency ratio = (32 ÷ 100) × 100 = 32.
12. In a town, there are 43 young dependants (under 15), 13 elderly dependants (65 and over), and 100 working-age residents (15–64). Calculate the total dependency ratio (dependants per 100 working-age people).
56
Total dependants = 43 + 13 = 56. Dependency ratio = (56 ÷ 100) × 100 = 56.
