During a 10 week summer vacation, was the average (arithmetic mean) number of books that Carolyn read per week greater than the average number of books that Jacob read per week?

(1) twice the average number of books that Carolyn read per week was greater than 5 less than twice the number of books that Jacob read per week.

(2) during the last 5 weeks of vacation, Carolyn read a total of 3 books more than Jacob.

E.

From (1), you have
C > J - 2.5
Say C=4, J=2.5, Yes
Say C=2, J=4, No
INSUFFICIENT

(2) This doesn't give the first 5 weeks, the numbers can be anything...
INSUFFICIENT

Together, more of the same.

I agree with your reasoning and also got E but the answer was A. I think the answer is wrong or this problem is worded very poorly.
