219. Sheep Division. A certain Australian farmer, on his deathbed, left his sheep to his three sons. Alfred is to receive $20 \%$ more than John and $25 \%$ more than Charles. John's share is 3600 sheep.

How many sheep will Charles receive? Perhaps the reader will be able to solve the problem in a few seconds.
219. Charles's share amounts to 3456 sheep. Some readers probably first found Alfred's share and then subtracted \(25 \%\), but such a solution is, of course, incorrect.
