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 of 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.






Please explain your answer. Also, I find such problems confuse me sometimes. Any fast or effective formulas to use when dealing with such problems?
Thanks
