Sathish ranks eighth in a class. What is his rank from the last?
I. There are 47 students in the class
II. Amsa who ranks 10th in the same class, ranks 38th from the last.
To find the rank from other end, we need to know the total number of student in the class, so I is sufficient.
Also from II we can conclude that there are 47 students in the class.
So II is also sufficient.
