  The proposed Iron Calorimeter (ICAL) detector at Indian Neutrino
Observatory(INO) will be a large (50 kt) magnetized detector located 1270 m
underground at Bodi West Hills in Tamilnadu. ICAL is capable of identifying the
charge of the particles. In this paper its potential for the measurement of the
muon charge ratio is explored by means of a detailed simulation-based study,
first using the CORSIKA code and then comparing it with an analytical model
(the "pika" model). The estimated muon charge ratio is in agreement with the
existing experimental observations, its measure can be extended by INO-ICAL up
to 10 TeV and up to 60 degrees.
