If Dale works at full efficiency he needs a break of 1 day after every 2 days of work and he completes a job in a total of 8 days. If he works at reduced efficiency, he can work without break and finish that same job in 8 days. Dale's output at reduced efficiency is what fraction of his output at full efficiency? Choose the correct choice: A) 4/12 B) 3/4 C) 6/5 D) 11/12 E) 5/6
We're told that there are 2 ways for Dale to complete a job:   1) Full Efficiency: 2 days of work followed by 1 dayofffor a total of 8 days.   2) Reduced Efficiency: 8 straight days with no days off.   Working at Full Efficiency creates the following pattern:   2 days on, 1 day OFF, 2 days on, 1 day OFF, 2 days on, 1 day OFF, 2 days on = 2+1+2+1+2=

8 days   Totals: 6 days on, 2 days off   Reduced Efficiency means that Dale will do 6 days of work in 8 days, thus those Reduceddaysare 6/8=3/4 of Full Efficiency.   Answer : 3/4

If Dale works at full efficiency he needs a break of 1 day after every 2 days of work and he completes a job in a total of 8 days. If he works at reduced efficiency, he can work without break and finish that same job in 8 days. Dale's output at reduced efficiency is what fraction of his output at full efficiency?
