If 70 percent of a country's population is aged 15-64 and total population is 80 million, what is the working-age population?

Answer and explanation

Correct answer: 56 million

The working-age group in this question is defined as people aged 15–64 years. To find how many people belong to that group, multiply the total population by 70 percent. Since 70 percent equals 0.70, the calculation is \(80\text{ million}\times0.70=56\text{ million}\). Therefore, the correct choice is B, 56 million, or 5.6 crore.

The conversion is also straightforward: one crore equals 10 million, so 56 million equals 5.6 crore. The remaining 30 percent is not part of the stated working-age group and should not be added. Options A, C, and D represent different percentages or incorrect multiplication results. This calculation gives the number of people in the specified age range; it does not claim that every person in that range is employed.
