Question: Gaurav ranks eighteenth from the top in a class. What is his rank from the last?

Statements:
1. There are 47 students in the class.
2. Jatin who ranks 10th in the same class, ranks 38th from the last.
Options
A. I alone is sufficient while II alone is not sufficient
B. II alone is sufficient while I alone is not sufficient
C. Either I or II is sufficient
D. Neither I nor II is sufficient
E. Both I and II are sufficient

Correct Answer

Either I or II is sufficient

Explanation

From I, we conclude that in a class of 47 students, Gaurav ranks 18th from the top and hence 30th from the last.

From II, we conclude that there are 9 students above and 37 students below Jatin in rank. Thus, there are (9 + 1 + 37) = 47 students in the class.

So, Gaurav who ranks 18th from the top, is 30th from the last.
