If elderly people form 14 percent and the working-age population 56 percent, approximately what is the elderly dependency ratio per 100 working-age persons?

Answer and explanation

Correct answer: About 25

The governing concept is the elderly dependency ratio, which compares the elderly population with the working-age population rather than with the total population. The formula is: elderly dependency ratio = (elderly population ÷ working-age population) × 100. Substituting the values gives (14 ÷ 56) × 100 = 0.25 × 100 = 25. Thus there are approximately 25 elderly people for every 100 working-age persons, so option C is correct. Option A mistakes the elderly share of the total population for the ratio. Option B does not result from the given division, and option D incorrectly uses the remaining population or another unrelated comparison.
