It is very difficult to get exact reply to complicated questions through RTI, because the concerned deptt almost always give the information specifically asked, and not the questions that may be considered to be implied.
For Mumbai-Ammedabad sector, The reply may include only the sale of tickets/ occupancy of seats at originating station only. Practically Mumbai-Ahm route is very high traffic density route and occupancy of just about 60% is hard to believe. Special fare/Premium trains may have poor occupancy due to high dynamic fares.
