### HideShow timer Statistics

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.

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.

IMO C

let set A be the set of people who feel they are more productive at home
let set B be the set of people who work less than 1 hour at home

P(A) = 90%
P(B) = 25%
let P(A union B) = 100%

So.. P(A union B) = P(A) + P(B) - P(A intersect B)
So.. P(A intersect B) = P(A) + P(B) - P(A union B)

So P(A intersect B) >= 90 + 25 - 100 = 15

P(A intersect B) is nothing but 15 percent of the office employees who do not define productivity exclusively in terms of the number of hours worked....It defines productivity both in terms of number of hours worked from home and in terms of number of hours worked less than 1 hour at home.

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.

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.

25% - actually work less than one hour
90% believe they are more productive working at home than working in their office.

25 + 90 = 115. Min overlap = 115 - 100 = 15% (They work less and do not define productivity in terms of 8 hr window)

c) 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?

Good thought and question. Like all the others, I have to choose C too.

But, I think becoming productive is in the nature of a person. It doesn't depend on the number of hours he/she has worked or on the place he/she is working at.

Letting an employee work from home is definitely a challenge though. That is because it is where a lot of distractions come from hence making them more unproductive. However, now that we have modern technology, with the right monitoring tools coupled with good management techniques, I'm sure the good work environment, even when employees are working from home will still be there.

I'd say C, too. The question is a little weird, though.

"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,"

.. and what about the other ones, those who do not work 8 hours each day or don't work at home at all? C states "the office employees", but i'd understand "the office employees" to be "all office employees", not only the ones working 8 hours a day and sometimes at home.

Go to an M&A company where 99% of the people are working like 16 hours a day, you couldn't say anything about "the employees" just by judging a small subset of people woring 8 hours daily.

C. 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.

IMO it is C guys. This is more of a mathematical problem.

Eliminate A and E as it is somewhat Out of scope. Now the battle is between B,C and D.

B- makes a brave statement about productivity that is not mentioned or can be inferred.
D-At least 25% can complete the same amount of work in 1hr?? where did they deduce this from
So the left out choice is C
The OA is C as well.

I have posted a picture too so that conclusion can be drawn easily.
As you can see that R1C1-> atleast 15% feel productive at home, a fact that these people do not define productivity in terms of number of hours worked.
Nice question though MGMAT.

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. OFS. Passage do not mention about the amount of work
e Some of the office employees make statements regarding their productivity that are not in fact true. We can not question the premise

Therefore, IMO C

Hey ,
It is true that this is a quant question , and the answer you have picked is correct though, but that is not how the analysis goes.

It says 90% of those same office employees ( i.e 25% of the total employee , who work less than an hr at home ) . Meaning - 90% of the 25% of total employees say they are more productive working at home .
So the calculation goes 90% * 25% = 22.5% of total employees ( notice that you do not need to do this calculation , but just need to realize that this is slightly less than 25% ). Hence option C gives you a far lower value than this i.e 15% and nothing like 22.5% or 23% , so it is obvious and you do not need to calculate.

You may have misread "of those same employees" to refer to 25% instead of the overall lot!

25% - 25 work less than 1 hour
90% - 90 find it more productive
Hence - (90+25)-100 = 15 is the overlap, who find it more productive and work less than 1 hour. Hence, these guys do not define productivity in terms of hours as they believe in completing the work rather than completing the required hours.

That is just incorrect interpretation . It is 90%of 25%=22.5%. However, option c is correct because it says at least 15%.
