If children form 38 percent of a country's population and the working-age group forms 57 percent, what percentage is elderly?

Answer and explanation

Correct answer: 5 percent

The three broad age groups together represent the entire population, so their percentages must add up to 100. The child group accounts for 38%, and the working-age group accounts for 57%. Their combined share is therefore 95%. The elderly share is whatever remains after these two groups are subtracted from the total.

The calculation is \(100-(38+57)=100-95=5\) percent. Hence, elderly people form 5% of the population, and option B is correct. This conclusion assumes that the three categories cover the whole population without overlap or an unlisted age group, which is the usual meaning of the age-structure data in the question. The other options do not satisfy the required total of 100%.
