Hi All,

There's a visual 'component' to this question that will probably help you to solve it.

We're told that there are 2 ways for Dale to complete a job:

1) Full Efficiency: 2 days of work followed by 1 day "off" for a total of 11 days.

2) Reduced Efficiency: 11 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+1+2 = 11 days

Totals: 8 days on, 3 days off

Reduced Efficiency means that Dale will do 8 days of work in 11 days, thus those Reduced "days" are 8/11 of Full Efficiency.

Final Answer:

GMAT assassins aren't born, they're made,
