C for me Suppose there are 100 employees. 90 out of the 100 people believe they are more productive at home than they are at work. 25 out of the 100 people work less than one hour on the day they work from home. The smallest possible overlap between these two subgroups of people is 15. So, among that overlap group, people who work less than one hour when at home, and yet also feel more productive. Hope this help !!!!!

Heart of the argument is - that there is some portion of office employees who feel they are productive irrespective of number of hours they work every day.
So basically we need to find percentage of those employees who rate their productivity exclusive to number of hours worked.
Options A,D and E can be completely eliminated since they are irrelevant.
Leaves me with option B and C.
B says 10% of employees (total employees) are less productive working from home. However as per premise maximum of [100% - 90%][25%][Total office employees]. This is definitely not 10%. Hence B cannot be correct answer choice.
Leaves me with option C.
90% of [25%] of employee feel they are productive irrespective of number of hours worked at home, which is around 22% of total employees. Hence at least 15% employee rate their productivity exclusive to number of hours worked.
Hence the correct answer choice is C.
Thanks,
Akhil M.Parekh

can u explain thiss? A = 90 percent of the office employees believe that they are more productive at home than at work. B = 25 percent of the office employees actually work fewer hours (<1 hr) when they work at home than when they work at the office (8 hrs). A intersection B = 100 - (90+25) = 15

There are 100 employees in company X
When working from home, 25% employees work less than 1 hour = 25 employees work less than 1 hour
over 90% of the employees believe they are productive = 90 or more than 90 (may be 90, 93, 94, 96 or 97 etc.) employees believe they are productive
Now suppose there are exactly 90 employees who believe they are productive and 10 employees believe they are not productive. And in the worst case, these 10 employees are from the group of 25 who work for 1 hour. That still leaves 15 employees to believe that they are productive even when they work for 1 hour.
And C exactly says that
At least 15 percent of the office employees do not define productivity exclusively in terms of the number of hours worked.

My doubt here is as follows:
According to a recent magazine article, of those office employees WHO typically work 8 hours at the office each day but sometimes say that they will work at home on a particular day.
Doesn't this mean that the office employees being discussed in the first place is NOT ALL office employees but only those who typically work 8 hours at the office each day but sometimes say they will work at home on a particular day. What about those office employees who work at the office each day but never mention about working at home on a particular day?
