Question #33 Knewton Free test
of the 310 cars manufactured by company X during the first quarter of last year, how many were sold by the end of that year?

1)Of all the cars manufactured by company X last year, 85 percent had sold by the end of that year.
2)A total of 1,900 cars manufactured by company X last year were sold by the end of that year.

OA is E

IMHO is B. It says that all the 1900 cars manufactured that yoear by the car company were sold out.
It implies that all the 310 (or whatever might be the number) cars manufactured by company X during the first quarter of last year were also sold out.

Pls correct me if i am wrong.

Thanks
Karthik

Your assumption is wrong. 1900 cars were sold. But nowhere in Stmt 2 does it say that only 1900 were produced.

Vineesh,
Just telling you what I know and think. I am not the expert.

Hi Karthik,

The statement in question:
2)A total of 1,900 cars manufactured by company X last year were sold by the end of that year.

This means that, of all the cars Company X manufactured last year, 1900 of them sold by the end of the year.

It's similar to saying, "A total of 13 students who graduated from Harvard in 2010 later became CEOs." This doesn't mean there were only 13 Harvard graduates in 2010.

I hope that helps.

Cheers,
Brent

My feeling is that if you read the information differently, then there are probably others who read it differently too.

The GMAT test-makers are pretty good at avoiding any ambiguity, so perhaps the question could be worded a little differently to avoid any confusion (something like, "Of all cars manufactured last year, 1900 were sold by the end of the year").

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
