I just analyzed what Ron Purewal had stated in his comments and made a chart to see how the numbers will play out. Whenver you encounter a problem with something increasing or decreasing, just simply put it on paper and then do an analysis. Otherwise, you'll be lost in the verbiage.EricKryk wrote:It does help. thank you. What do you use to study CR?mbadrew wrote:
Sami,
Let's analyze the conclusion, " Since a rising per capita GDP indicates a
rising average standard of living, the average standard of living in Country A must have risen between 1980 and 1990". Now A states that the population of both countries increased. If that was the case then the difference will still be $5000 and not $6000. For example if country A has 10 people and country B has 10 people and difference in per capita GDP is $5000 to begin with, then if the population of bother countries increased, for example country A=12 people, country B= 12 people, the per capita will not rise, rather it'll remain constant or proportionately decrease, but not reflecting change in proportion for both countries.
I hope this helps.
Manhattan gmat books and princeton review book has helped me pull things together. I'm also using GMAX online review course, which in my opinion is similar to the MGMAT review material.
