Plz prep_gmat can you explain how you see that then the second highest sales must be greater than 11.
can we have the OA thanks
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.
