Ans: C

Sat = 38

Th = 8

F = ?

The remaining days (the cutoff number is 11)

day1=10
day2=9
day3=7
day4=6

Total = day1 +day2 + day3 +day4+Sat+Th =78
F= 90-78

B.

St1: You can arbitrarily increase or decrease saturday's sale to either sell more or less(or equal) than/to 11 books.

St2: If Saturday is 38, then the second highest sales must be greater than 11. Sufficient.

Sure, we don't care about how many books were sold on Thursday. B is sufficient.

well lets see if T=90 books

38 sold on saturday, then 52 will be sold in the remaining 6 days..

say if we 8*5=40, then on Firday we sold 12 books.

say if we sold 11 books on friday then we will have

52-11=41 books sold in the 5 remaining days
which means the store could sell 9 books one day and 8 books each on the remaining day..

so from this above, St (1) and ST(2) are totally useless and combining them is also useless...

we need to know if on Friday we sold more than 11 books, with the above reasoning I am showing that on Friday the number of books sold could be 11 or more than 11...but we cannot clearly say that it is more than 11...

The statements are more useful than given to believe.

The flaw in your approach is that you did not consider the term 'different' in the question.

The total number of copies sold on other days other than Saturday is 90 - 38 = 52
Since Friday had the second highest sales. Try plugging in 11 for Friday and decrement 1 for all the other days and you will find that it will be less than 52, which means Friday's had to have been more than 11.
