Store S sold a total of 90 copies of a certain book during the seven days of last week and it sold different number of copies on any two of the days. If for the seven days Store S sold the greatest number of copies on Saturday and the second greatest number of copies on Friday, did Store S sell more than 11 copies on Friday?

1. Last week Store S sold 8 copies of the book on Thursday
2. Last week Store S sold 38 copies of the book on Saturday
