In a town, 60% of the population are adults, and the rest are children. If 40% of the adults are male, and the total population is 5000, how many adult females are there?

✓ Correct Answer: Option B

Total population = 5000. Adults = 60% of 5000 = 0.60 * 5000 = 3000. If 40% of adults are male, then 100% - 40% = 60% of adults are female. Adult females = 60% of 3000 = 0.60 * 3000 = 1800.
