Greener Pastures
A problem supposedly posed by the great Isaac Newton:
Three pastures with grass of identical height, density, and growth rate are of size 3 1/3 acres, 10 acres, and 24 acres, respectively, If 12 oxen can be fed on the first pasture for 4 weeks and 21 oxen can be fed on the second for 9 weeks, how many oxen can be fed on the third pasture for 18 weeks?
