According to a recent magazine article, of those office [#permalink]
05 Dec 2008, 06:10
33% (02:04) correct
67% (01:30) wrong based on 5 sessions
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.
Yes, it should be C. This is really just a Venn diagram question - we know 25% of a certain group work less than an hour per day, and that more than 90% of the same group say they are more productive from home. Well those percentages add to more than 100%, so these two groups need to overlap somehow - it must be that at least 90+25-100 = 15% of these people *both* work less than an hour per day and claim to be more productive. Answer choice C follows from here.
And there's something wrong with the wording of the stem (it seems like a few words are missing), but I gather everyone has understood what it's trying to say.
