Three brothers Adam, Barnaby and Charles are each granted a share of their father’s estate upon his death, such that the eldest brother Adam receives the most, the next eldest Barnaby a lesser amount, the third son Charles the least.

Charles comes up with a scheme such that there will be three rounds of redistribution.

Firstly Charles takes half of his share and splits it equally between the other two. Then Barnaby does the same, and finally Adam does likewise.

Miraculously they all end up with the exact same amount!

If instead, they did the exact same procedure but beginning with Adam, and proceeding through Barnaby, then Charles, Adam would end up with £19,881 more than Charles.

How much were they each granted in the will?
