Question 329016: You have been hired by a group of anthropologists to sort out the data that they collected from a trip to Ja-Ji, a remote island in the south Pacific. The people of Ja-Ji do not permit outsiders to count them directly; so, the anthropologists had to collect all sort of other data to get to the population. They fear that they may have missed something and your job is to make that assessment, or better yet, use what they have to get the population of Ja-Ji. This is what their notes say:
People in Ja-Ji are either single or in monogamous unions. 10% of the adult population of Ja-Ji is homosexual and they are all in long term relationships. These homosexual unions constitute one fifth of the unions in Ja-Ji. There are 1,000 children, which constitute half of the single population of Ja-Ji.
HOW DO I SET THIS ONE UP?

You can put this solution on YOUR website! maybe just reason it out
"There are 1,000 children, which constitute half of the single population of Ja-Ji."
___ so the other half of the single population is 1000 adults
"10% of the adult population of Ja-Ji is homosexual and they are all in long term relationships"
"These homosexual unions constitute one fifth of the unions in Ja-Ji"
1/5 of the unions is 10% of the adult population ___ so all the unions (5/5) is 50% of the adult population
half (50%) of the adult population is in unions , so half is single (those 1000 adults that are half of the single population)
1000 people are children
___ 1000 people are single adults
___ 1000 people are paired adults ___ 200 of which are homosexual
total population ___ 3000
