If a country has a total population of 100 million, with children forming 23 percent and elderly people 17 percent, what is the absolute working-age population?

Answer and explanation

Correct answer: 60 million

The child and elderly groups together make up \(23\%+17\%=40\%\) of the total population. The remaining share is the working-age population: \(100\%-40\%=60\%\). Since the total population is 100 million, the working-age population is \(0.60\times100=60\) million.

Therefore, option B, 60 million or 6 crore, is correct. The options use both million and crore notation: 60 million equals 6 crore because 1 crore equals 10 million. The calculation asks for an absolute number, so giving only 60 percent would be incomplete. The result assumes the three age groups together cover the whole population without overlap.
