Question 2
Together Jack and his wife consume a barrel of fat in 60 days; Jack alone takes 30 weeks. Together they consume a barrel of lean in 8 weeks; his wife alone takes 40 weeks. A barrel contains half fat and half lean. Jack eats lean whenever available; his wife eats fat whenever available. When one kind runs out, both eat the remaining kind. How long to finish? AI reconstruction: the original nursery-rhyme claim that each “could eat no” other kind is treated as a preference, not inability; the finite rates are constant, one week is 7 days, and the two halves are measured in equal barrel units.
