I had to prepare a document mentioning the softwares installed in my development environment. I was able to find the version number of other softwares. But in sharepoint its not quite straight forward and need to follow the below steps to find the exact version number

1.Go to central admin
2.Click on the Operations tab
3.Click on "servers in form" option under Topology and Services section
4.It should display the list of servers available in that farm as well as the version number of MOSS installed on those servers.
