मंगलयान (Maṅgalayāna) is due to launch on November 05, 2013 AD of the Gregorian Calendar at 1436H (GMT+0530). Wikipedia writes to say
The November 2013 launch will place the Mars Orbiter Mission into Earth orbit, then six engine firings will raise that orbit to one with an apogee of 215,000 km and a perigee of 600 km, where it will remain for about 25 days. A final firing in 30 November 2013 will send MOM onto an interplanetary trajectory.
The same article goes on to write
The spacecraft's dry mass is planned to be 500 kg, and it will carry 850 kg of propellant and oxidiser.
I'm no rocket-man; what fraction of the 850KG is expected to be consumed during the course of transfer, and correction burn? Put another way, how much fuel will remain available to enter Mars' orbit?
