If 25 percent of a country's population is aged 0-14 and 15 percent is aged 60 and above, what percentage is aged 15-59?

Answer and explanation

Correct answer: 60 percent

The governing concept is that the major age groups together account for 100 percent of the population. The child group contributes 25 percent and the elderly group contributes 15 percent, so their combined share is 25 + 15 = 40 percent. The remaining share belongs to the 15–59 age group: 100 − 40 = 60 percent. Therefore, option A is correct. Option B would leave 10 percent unaccounted for, while option C incorrectly treats the combined child and elderly share as the working-age share. Option D is impossible because it would make the total exceed 100 percent when added to the given groups. The calculation assumes the three stated age intervals cover the population without overlap or omission.
