Dear Harshavardhan02156, in this changeset you have removed a lot of detailed residential areas and replaced them with much more coarsely drawn versions that are less accurate. Please don't do that. I will revert this edit. 

When you add new residential areas you can choose how precise you want to be, and drawing a coarse area is ok, but it is NOT ok to remove an area that someone else has drawn with great attention to detail and replace it with a lesser quality one.

Also, in your changeset comments, please use a good description of your edits, not "Updated" - that is a description that fits 99% of all edits made in OSM. See https://wiki.openstreetmap.org/wiki/Good_changeset_comments for an in-depth explanation.
