alleryA(4 h) and B(3 h) start together. C(5 h) needs A; D(4 h) needs B. C and D share one machine. E(2 h) needs both C and D. Earliest finish?
A14 h
B11 h
C15 h
D16 h
Answer & Solution
Correct answer: A. 14 h
Run D on the shared machine from 3–7 h, then C from 7–12 h, then E from 12–14 h. Running C first instead finishes at 15 h, so the minimum is 14 h.
