Dear Ripti Verma,
I always advice to the members "before raising any query it is better to first search the document-information and put extra efforts to resolve your query". However, if you don't get relevant information then only raise your query with relevant information.
Since you are new in the forum, may be not aware how to get desired information. Hence I am sharing the below docs
1. Delhi MW Notification = Rates applicable from Oct'20 to Mar'21.
2. Delhi MW Notification = Rates applicable from Apr'21 to Sep'21.
3. Haryana MW Notification = Rates applicable from Jan'21 to Jun'21.
Hope the attached documents will serve your purpose.
