Hi Anamika, 

adding a detail to Peter's excellent answer:

For newer versions of Galaxy (while it is running) you can go to the url `your.galaxy.com/api/version` to learn the release of Galaxy you have.

Thanks for using Galaxy,

Martin

Galaxy was originally distributed via the mercurial (hg) version

Try this (which will work on a very old Galaxy using hg),

$ hg log | head
changeset:   17125:e837a68e8d14
tag:         tip
parent:      17121:7a4e3a661a76

...

If that fails, try this which will work on a Galaxy distributed with git:

$ git log | head
commit cbd527b9a4671c7abe9a22cf69e869b5d2de858a
Merge: 33dec01 d0f39ce
Author: Nicola Soranzo <nicola.soranzo@earlham.ac.uk>
Date:   Wed Dec 7 20:35:40 2016 +0000

    Merge branch 'release_16.10' into dev

    Conflicts:
            static/scripts/bundled/analysis.bundled.js
            static/scripts/bundled/analysis.bundled.js.map
...


If it isn't clear from the commit message, you can then match those commits
to the relevant repository and hopefully work it out, here those were:

https://bitbucket.org/galaxy/galaxy-central/commits/e837a68e8d14

and

https://github.com/galaxyproject/galaxy/commits/cbd527b9a4671c7abe9a22cf69e869b5d2de858a

If neither git nor hg work, then perhaps your Galaxy was installed via a
different route - and that will likely complicate updating it.
