What if the GDP of EEC had fallen by 1000 in 1990
in that case the difference doesnot account for a rise in standard of living

IMO A
premise 1 - diff in GDP $5000 Assumption - population increase at same % premise 2 - diff in GDP now$6000
Conclusion - Living standard definately increased

What is OA?

Its D,

logic being.

Lets assume there are 2 numbers A and B . The difference between them is 5.
A- B = 5.

after say some mathematical operation the difference became 6
A-B = 6.

So, the difference rose by 1. Now this is only possible in 2 cases.

either A increased or B decreased.

Only way A could have increased is incase B either remained constant or the decrease in B was less than 1.

So D holds true, if the GDP of Eu was not lower than 1000 in 1990 then that means there was some increase in GDP of country A and so the standard of living improved.

The answer D although is the best correct one, it has some flaw in reasoning.
Answer D says that GDP per capita in EU did not decrease by no more than $1 000 in 1990 than in 1990. If the decrease was lower than$1000, the assumption would hold perfectly true, since for 6000 increase in difference to hold true, at most $999 drop in GDP per capita of EU is necessary at worst case scenario. The answer D assumes that the drop in GDP per capita in EU could be straight$1000
Thus let's say GDP per capita in 1980 in country A was $6000 and in EU$ 1000
Then let's say in 1990 it was still $6000 for Country A and EU's GDP per capita dropped to zero! (We can assume that from answer D). The conclusion that living standards improved in country A will not hold true then, as u can see from my example. D is the best answer but it has the above mentioned flaw, what do u guys think? _________________ Never give up,,, Director Joined: 24 Aug 2007 Posts: 954 WE 1: 3.5 yrs IT WE 2: 2.5 yrs Retail chain Followers: 76 Kudos [?]: 1272 [0], given: 40 Re: GDPs of Country A and EEC [#permalink] ### Show Tags 09 Jun 2010, 04:50 OA is D. _________________ Want to improve your CR: http://gmatclub.com/forum/cr-methods-an-approach-to-find-the-best-answers-93146.html Tricky Quant problems: http://gmatclub.com/forum/50-tricky-questions-92834.html Important Grammer Fundamentals: http://gmatclub.com/forum/key-fundamentals-of-grammer-our-crucial-learnings-on-sc-93659.html GMAT Club Legend Joined: 01 Oct 2013 Posts: 10540 Followers: 919 Kudos [?]: 204 [0], given: 0 Re: Really tough one from Powerscore CR Bible.

EEC [#permalink] ### Show Tags 07 Sep 2016, 06:49 Got confused by this one. I selected A. The difference of the GDP between Country A and EEC changes only if A increases and EEC remains stable, A increases more than EEC A decreases less than EEC A remains stable and EEC decreases. D says that the per capita GDP for EEC is not more than 1,000$ lower in 1990 than that of 1980.
Is not more than 1,000$lower means that it could be 1$,100$or 999$ lower.
But what if it is exactly 1,000$lower? In this case if A remains stable and EEC decreases 1,000$, the difference between A and EEC is 5,000 + 1,000=6,000\$.
So it could be or could be not true.

In fact, in order to make a comparison between these two GDPs, its a prerequisite that we are talking about the same populations as we did 10 years ago.
We can't compare country A with EEC, when in country a the population decreased by 50% (and thus the GDP rose), with EEC who faced a population increase.

IMO A.

please tell me what i might have misunderstood.
