In Ranking Sequence questions, ranks of a person both from the top and bottom are mentioned and total number of persons is asked. However, sometimes this question is put in the form of a puzzle of interchanging seats by two persons.
Aruna ranks twelfth in a class of forty-six. What will be her rank from the last?
Number of students behind Aruna in rank = (46 - 12) = 34. So, Arun is 35th from the last.
