CR - Work efficiency at home

Expert replies

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, 25 percent actually work less than one hour. At the same time, over 90 percent of those same office employees believe they are more productive working at home than working in their office.

The statements above, if true, best support which of the following conclusions about the office employees discussed in the article?

a) On average, the office employees working at home for a day work fewer hours than office employees working at the office.
b) 10 percent of the office employees are less productive working from home than working in their office.
c) At least 15 percent of the office employees do not define productivity exclusively in terms of the number of hours worked.
d) At least 25 percent of the office employees can complete the same amount of work in one hour at home as in 8 hours at the office.
e) Some of the office employees make statements regarding their productivity that are not in fact true.

Can someone provide an answer for this one?

Will disclose OA after some replies are posted.

A

The C through D include additional facts, and E seems too broad.

The OA is C and the explanation is as follows (though I admit I got lost on this one)

(C) CORRECT. 90 percent of the office employees believe that they are more productive at home than at work. At the same time, 25 percent of the office employees actually work fewer hours when they work at home than when they work at the office. The overlap between these two groups is at least 15 percent of all of the office employees. This group of employees believes that they are more productive at home than at work and yet this group actually works fewer hours at home than at work. Thus, these employees must not define productivity exclusively in terms of the number of hours worked.

I've heard that GMAC never tests CR with arithmetic, so I assumed B, C, D were out of the picture.

Where was this question from?

I picked "C" as well.
The reason was, this was a paradoxical situation, and only way both could be true if employee dose not define productivity in terms of # of hrs worked. for me 15% just provided additional point didn't looked in to that very seriously.
