If a country's child population is 36 percent and elderly population is 8 percent, what percentage of the population remains in the working-age group?

Answer and explanation

Correct answer: 56 percent

The three broad age groups together account for the entire population, or 100 percent. Children make up 36 percent and elderly people make up 8 percent. Their combined share is therefore \(36+8=44\) percent. The remaining share belongs to the working-age group, so it is \(100-44=56\) percent. Equivalently, the calculation can be written as \(100-(36+8)=56\) percent.

Hence, option B is correct. The question asks for the proportion left after removing both dependent groups, not for the sum of children and elderly people. Option A is the dependent share, 44 percent, while option C subtracts only the child population and ignores the elderly group. Option D has no basis in the given figures. This calculation assumes that the stated child, elderly, and working-age categories are mutually exclusive and together cover the full population.
