GMAT Question of The Day: Critical Reasoning

The U.S. census is not perfect: thousands of Americans probably go uncounted. However, the basic statistical portrait of the nation painted by the census is accurate. Certainly some of the poor go uncounted, particularly the homeless; but some of the rich go uncounted as well, because they are often abroad or traveling between one residence and another.

Which of the following is an assumption on which the argument above depends?

(A) Both the rich and the poor have personal and economic reasons to avoid being counted by the census.
(B) All Americans may reasonably be classified as either poor or rich.
(C) The percentage of poor Americans uncounted by the census is close to the percentage of rich Americans uncounted.
(D) The number of homeless Americans is approximately equal to the number of rich Americans.
(E) The primary purpose of the census is to analyze the economic status of the American population.

  3. mukund says:

  4. GOPI says:

    it is c

  5. Amishe800 says:

    See its ‘C’

  6. aravind says:

    i think the answer is ‘E’ or ‘C’. But more probable is E. can anyone say why E is wrong?

  7. DC800 says:

    E is the wrong answer but a correct statement. It’s a definition. The author’s argument is not based on the definition of what the census is, but rather if it is an accurate portrayal of the American population when you take into consideration that not every single person is included in the data analysis.

    The correct answer is C

  8. Biplav says:

    D, but C may also be correct

  9. Nik says:

    C is correct..

    D is not correct as if there are 10 rich people and 100 poor ppl (say..)
    if 10 rich and 10 poor are travelling.Then the statistics are obviously wrong.
    But if you say 10 % then we have 1 rich and 10 poor on the road.
    So it still gives the correct statistics

  10. robin says:

    ans is C
    let we have 100 poor and 50 rich
    now % of rich=33
    %poor=67
    if 10 persons both poor and rich are not counted than
    no of rich counted=40
    no of poor counted=90
    % rich
