Nearly all mail that is correctly addressed arrives at its destination within two business days of being sent. In fact, correctly addressed mail takes longer than this only when it is damaged in transit. Overall, however, most mail arrives three business days or more after being sent. If the statements above are true, which one of the following must be true?
(A) A large proportion of the mail that is correctly addressed is damaged in transit. (B) No incorrectly addressed mail arrives within two business days of being sent. (C) Most mail that arrives within two business days of being sent is correctly addressed. (D) A large proportion of mail is incorrectly addressed. (E) More mail arrives within two business days of being sent than arrives between two and three business days after being sent.
I think D can reasonably be inferred, but I'm not too confident...
(None of the answers must be true, IMO.)
I too agree that none of the answers stands out.
May attempt at refuting (D) : There can be an inherent problem in postal transit the system that causes most mail to be damaged and hence they are delayed. So (D) need not be true.
I agree. Also, we don't know how long it takes for incorrectly addressed mail to arrive. Suppose it takes 20 days to arrive: then there should be very few of these in order for the average to be 3 days.
Nearly all mail that is correctly addressed arrives at its destination within two business days of being sent.
In fact, correctly addressed mail takes longer than this only when it is damaged in transit.
Since nearly all correctly addressed mail arrives on time, it follows that the postal service damages very little mail.
If the postal service damages very little mail, and damage and mis-addressing are the two things that keep mail from taking 3+ days for delivery (which happens the majority of the time), than misaddressing is the only possible culprit.
And the refutation that I thought of for D doesn't hold water...
