If elderly people form 28 percent and working-age people 58 percent of a country's population, what are the child share and total dependent share?

Answer and explanation

Correct answer: 14 percent and 42 percent

The three age groups together make up the entire population, or 100 percent. The working-age share is 58 percent and the elderly share is 28 percent. The child share is therefore the part left after subtracting these two groups from 100 percent: \(100-58-28=14\) percent.

Total dependents include both children and elderly people. Adding their shares gives \(14+28=42\) percent. Thus, children form 14 percent of the population and all dependents together form 42 percent. Option A gives exactly this pair. Option B incorrectly treats the elderly share as the child share, while the other choices do not satisfy the population total.
