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 average number of books that Jacob read per week.

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

Is C > J?

(1) Twice the average number of books that Carolyn read per week was greater than 5 less than twice the average number of books that Jacob read per week. (Assuming that average weekly consumption is same).
2C/10 > 2J/10 - 5
C > J - 50
May be case as C can be so large as to be more than J but it can also be so small that J is bigger than it.

(2) During the last 5 weeks of the vacation, Carolyn read a total of 3 books more than Jacob.
Not sufficient at all. Data of first 5 weeks missing.

Combining them is not going to yield any data either. So IMO E.

However, this question was discussed earlier and OA given was A but there was a dispute for the same.
