Dear Sunil,
You have to deduct PF on the Basic+DA part of the salary. There is no chart for this as the Basic+DA (if any) in your company would be guided by the States in which you have employed people. You will have to follow the Minimum Wages of each State where your people are employed. In the States' Minimum Wages, there would be this component of Basic + DA on which you have to pay PF (Employer + Employee share).
Note: In some States, the DA component is merged into Basic, hence you would only see the Basic component. Please don't get confused.
Regards
