In a village, 5/8 of the population is adults, 1/2 of the adults are male, and 4/5 of adult females are illiterate. If 400 adult females are illiterate, what is the population of the village?

1600 people

Explanation:

Since 1/2 of the adults are male that means 1/2 of the population is female.

So 5/8*1/2=5/16 of the total population are adult females.

And 4/5 of those adult females are illiterate so:

5/16*4/5=20/80=1/4

Since 400 adult females are illiterate, then:

1/4=400/x where x=total population

Thus x=1600 total people.
