As normal....read the question carefully.....

do they want GRID MINIMUM OFF-ROUTE ALTITUDE - in this case the higher of 2700ft and 3200ft

or do they want MINIMUM ENROUTE ALTITUDE - the altitude or FL marked on the airway

or do they want MINIMUM OFF-ROUTE ALTITUDE - the altitude with an 'a' after it on the airway.......etc etc.

Definitions of these altitudes can be found in the CHART GLOSSARY at the front of the JEPP MANUAL, and also page 57 of the ENROUTE CHART LEGEND is useful.
