Could someone please help me with this IR question from GMAT Exam Prep 2?

Why is part 1 not "Can be determined"? Isn't it 30% from the passage?

It seems to be all semantics (or word choice) to me. The paragraph talks about the 30% of revenue the railroads contributed to tracks, bridges and tunnels, while the question asks about tracks and machinery.

Hi,

The argument states that the railroads reinvested approximately 30% of their total revenue on tracks and machinery.

Approximately 30% means that the answer can take any value between 25% and 34%. So we cannot infer the exact percentage. Answer is 'Cannot be Determined'.

How confident are you on this? I want to make sure I watch out for this trap in the future if this is in fact the correct rationale for this being "Cannot be Determined" and there is no other reason.

I think this is incorrect because the next sentence does specify "tracks and machinery" when talking about the percent of revenue spent.

The question ask only for "maintain" the tracks and machinery, where as in the passage it is maintain and improve.
Hence it cannot be determined.

Yeah I was leaning towards this explanation too. Still seems to be very nit-picky.

I made the same mistake. I believe the passage says from year X to Y, where the statement says the machinery from From X to Y.
2 different meanings hence cannot be determined.

Agree with this. If we use the "Approximate" logic, we will not be able to determine answer to the 3rd question.

This is a stupid question. What is the difference between "maintain" and "improve"? Can improving the tracks not also be considered a form of maintenance? I don't understand what the GMAT is going for with these questions...

I disagree, the third question specifically requests for approximate figure....

Folks,

This is a very odd question. Don't worry about it much. The only explanation is "maintain" vs "maintain and improve". Usually IR questions are not this weird. Just make sure you pay attention to detail in general.

It says " Approximately" 30 % . If you look at the 3rd question it asks "Approximately how much revenue? " Hence, the first one is cannot be determined and the 3rd one can be determined.

Hi Sk1007,

the answer to this one is as follows:

The latter part of the paragraph under the "rail advocate" section states that "shifting 10 percent of the long-distance freight that currently moves only by truck to rail instead would save 4 billion liters of fuel per year". The question is asking for "the total amount of fuel that would be saved in the next 5 years if half of the long-haul freight that currently moves by truck were instead moved by train".

So if 10% conversion equals 4 billion saved per year, then 50% conversion (as the question asks for "half") would saved 5x, or 20 billion liters per year, and over 5 years this would constitute 20*5 = 100 billion liters saved in total.

Hope this helps.

Shifting 10% saves 4 billion per year, therefore 50% saves 20 billion per year. Over a five year period that is 5 * 20 = 100 billion

Question no:1 can’t be determined.
Reason:
In Passage it is given 30% invest in improve and maintain.

Question is asking for only maintenance.
Passage clearly mentioned that improve means laying additional rail track. (To replace truck transport by rail).

So investment in maintenance can’t be determined.

10% results in savings of 4bn litres per year
so 50% (As asked for) equals 20bn per year.

Hence in 5 years, it equals 20*5=100bn litres

Hope it helps
