Fred and Bill are elderly brothers. They are unmarried and have no children and each has savings of $18,000 as his only assets. They each decide to
make wills.
Fred's will leaves half his possessions to Bill, a quarter to the lifeboat
association and a quarter to the cats' defense league.
Bill's will leaves one-third of his possessions to Fred, a third to cancer
research and a third to the lifeboat association.
But when the second one dies, his assets will be divided equally between his
two chosen charities.
If Bill dies first, how much will the lifeboat association receive in total from
both Bill and Fred?
