If a country has a total population of 50 million and 16 percent are aged 65 and above, how many elderly people are there?

Answer and explanation

Correct answer: 8 million

The elderly population is found by multiplying the total population by the proportion aged 65 and above. The calculation is 50 million × 16 ÷ 100 = 8 million. In the Indian numbering system, 50 million equals 5 crore, and 8 million equals 80 lakh. Therefore, option C is correct. Option A represents 12 percent of 50 million, option B represents 14 percent, and option D represents 18 percent, so none of those values matches the stated 16 percent. The calculation assumes that the given percentage applies to the entire population and that the units are converted consistently.
