There is no way to circumvent this, since it's a feature intended to secure the information on your MacBook Air should it be lost or stolen.

Erase it using OS X Recovery, and restore its content from a backup.

Thanks John, the machine is now in service center and the people there are still wondering how can they do it. They told me that the recovery option would not work as the device has been locked by findmyiPhone app , and due to this they wont be able to do that. Can you guide me to how to use OS X Recovery , also the device is new so i haven't created any backup yet neither it has any data. First i was not able to get through the firmware password but now the apple support guys have sorted that but now i am stuck with the passcode.

A Mac that has been locked with a firmware passcode is an additional obstacle to overcome, since it can only be removed by an Apple Store or AASP. Refer to the following:

MacBook Air (Original), MacBook Air (Late 2008), and MacBook Air (Mid 2009): Recovering a lost EFI firmware password
MacBook Air (Late 2010) and later, MacBook Pro (Early 2011) and later, iMac (Mid 2011) and later, Mac mini (Mid 2011), Mac Pro (Late 2013): Recovering a lost firmware password

After they remove it, boot OS X Recovery and erase its internal storage by following these instructions:

OS X Mavericks: Erase and reinstall OS X - Apple Support

It stands to reason the Apple Store would probably do it for you, as part of the above service.
