renukishor,

If you're looking to find out which update may have impacted a site, Moz's Google Algorithm Change History is a good resource.  If a site was hit by a penalty, you can look back over a site's stats and take note of when a drop in visitors took place, then you can match that drop up with the date of an update and read more about the specifics of that update.

I have read this blog given by you but i not clear this Updates. What does it means mentioned in the bracket of Panda Updates For example :

1. Panda Update 1, Feb. 24, 2011 (11.8% of queries; announced; English in US only)
2. Panda Update 2, April 11, 2011 (2% of queries; announced; rolled out in English internationally)

what is the meaning of this (11.8% of queries; announced; English in US only). I am confused of Panda updates.
 Please clarify this Updates of Panda.

the percentage is how many queries are affected, this means that 11.8% of them were affected (this can be negative or positively or resulted in a penalty etc.)

The reason there are panda 1 and 2 is its a bit like a software update it gets better so it gets a new number each time. If you want more in-depth things on the panda there is loads of resource over the internet or Moz and only a quick search away.

Hope it helps.
