Victor's job requires him to complete a series of identical jobs. If Victor is supervised at work, he finishes each job three days faster than if he is unsupervised. If Victor works for 144 days and is supervised for half the time, he will finish a total of 36 jobs. How long Q would it take Victor to complete 10 jobs without any supervision?	Choose the correct choice.
A) 34	B) 52	C) 60	D) 70	E) 92
Rate when supervised = (job)/(time) = 1/t.   Rate when unsupervised = (job)/(time) = 1/(t+3).   For  144/2=

72 days he is unsupervised and does 36 jobs:   72/t + 72/(t+3)= 36 --&gt; t=3 days --&gt; t+3 = 6 days.   Victor to complete 10 jobs without any supervision will need Q 10(t + 3) = 60 days.   Answer: 60.
