Hi vishvanatha_achary,
I suggest you to watch this video http://www.asp.net/web-forms/videos/aspnet-35/aspnet-ajax/using-script-combining-to-improve-ajax-performance which demonstrate how to combine only those scripts that are needed on a page using ScriptReferenceProfiler.
ScriptReferenceProfiler can be downloaded from here: http://aspnet.codeplex.com/releases/view/13356
Hope this helps
