If children form 20 percent and elderly people form 20 percent of a country's population, what is the working-age share?

Answer and explanation

Correct answer: 60 percent

The population as a whole represents 100 percent. Children and elderly people are commonly treated as dependent age groups, while the remaining share belongs to the working-age group. To find that remaining share, add the two dependent groups and subtract their total from 100 percent.

Children account for 20 percent and elderly people also account for 20 percent. Their combined share is \(20+20=40\) percent. Therefore, the working-age share is \(100-40=60\) percent. This makes option C correct. The calculation assumes that the three stated age groups together cover the entire population without overlap or a missing category.
