Question

In a village, ⅝ of the population is adults, ½ of the adults are male, and ⅘ of adults females are illiterate. If 400 adult females are illiterate, then population of the village is?​

Answer 1

Answer:

1600

Step-by-step 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.
