You don't like to do homework by yourself, right?

http://manpages.ubuntu.com/manpages/trusty/man1/gvfs-mime.1.html

"DESCRIPTION

       gvfs-mime can query information about applications that are
       registered to handle a mime-type, or set the default handler for
       a mime-type.

       Gvfs obtains this information from the shared-mime-info database.
       The default handler is stored per-user, in the file
       $XDG_DATA_HOME/applications/mimeapps.list.

       MIMETYPE should be a mime-type such as text/plain or
       application/mbox. HANDLER should be the name of an existing
       desktop file such as gedit.desktop."

Most likely ~/.local/share/applications/mimeapps.list .

"OPTIONS

       The following options are understood:

       -h, --help
           Prints a short help text and exits.

       --query
           Query the handler for MIMETYPE.

       --set
           Set the default handler for MIMETYPE to HANDLER."

"NOTES

        1. Shared MIME-Info specification
           http://freedesktop.org/wiki/Specifications/shared-mime-info-spec"

IOW at least consider to use something such as MIME-Editor.

But most likely this is the easiest way to go:
