Question from a Princeton Review CAT

by Svedankae » Tue Aug 11, 2009 4:11 am
A certain telephone company practices “peakload pricing,” wherein it charges more per minute of usage during limited peak hours than during non-peak hours. However, the revenue generated by telephone calls made during non-peak hours is much greater than that generated by calls made during peak hours.

Which of the following, if true, would most effectively resolve the apparent discrepancy in the argument above?



A) The average length of a telephone call made during non-peak hours is greater than that of those made during peak hours.



B) The company billed customers for more minutes of non-peak hour conversation than minutes of peak-hour conversation.



C) The higher rate for peak-hour calls more than compensates for the fewer minutes of peak-hour conversation.



D) The average cost to the telephone company of a peak minute of conversation exceeds the average cost to the telephone company of a non-peak minute.



E) The total number of non-peak hour phone calls exceeds the total number of peak-hour phone calls.


Official Answer B

I had D because i believe it resolves the discrepancy by denoting that people spoke more in Non peak Hours than Peak hours but some one gotta confirm.

average length is a very vague term

B) The company billed customers for more minutes of non-peak hour conversation than minutes of peak-hour conversation.

stem speaks about per minute charge and this choice resolves the issue properly

C) The higher rate for peak-hour calls more than compensates for the fewer minutes of peak-hour conversation.

???????????????????? speak something else

D) The average cost to the telephone company of a peak minute of conversation exceeds the average cost to the telephone company of a non-peak minute.

where from does average cost come here? all the
question talks about revenue.


E) The total number of non-peak hour phone calls exceeds the total number of peak-hour phone calls.

better not to mix up 'total numbers' and 'per minute'

i dont get it.

in the stem they say that the price per minute during peak hours is higher than the price per minute in non-peak hours.

in choice B they say that there were more minutes of non peak hour conversation than there were minutes of peak hour conversation.

as far as i am concerned this does not resolve the discrepancy as choice B by no means says that the more minutes overcompensate for the lower price. by this logic answer A is just as correct as answer B.

isnt it? what am i missing?

Answer B seems to be logical one out of other answer choices
