Pre-RMO 2013 (Mumbai region)
There were two different sets of question papers -- set A and set B. The questions in set B are just a permutation of those in set A. Below are the links to both these sets. Please note that Questions 10, 14 and 17 in set A (Questions 7, 11 and 18 in set B) were withdrawn because of the ambiguity in the wording of the problems. See the answer keys below for more information about these.
