Kindly suggest ...How much should an injured employee be paid if was injured at work place on 2nd sep and was not at at work for 20 days and joined back on 24th sep. Note: The company also provided the complete medication.

Is there any legal rule related to this matter.

whether you are eligible for the compensation or not, depends on the nature of your employment (whether u fall under the definition of workmen or not under the Workmen's compensation Act) refer: http://www.vakilno1.com/bareacts/workmenscompensationact/s2.htm

again, please refer the below link for employers liability for payment of compensation.
