Hi Ashok,
You can either use roll-up summary field or formula field. 

For roll-up summary field refer to :http://https://help.salesforce.com/apex/HTViewHelpDoc?id=fields_about_roll_up_summary_fields.htm&language=en (http://https://help.salesforce.com/apex/HTViewHelpDoc?id=fields_about_roll_up_summary_fields.htm&language=en)
And for formula field refer to : http://resources.docs.salesforce.com/198/0/en-us/sfdc/pdf/salesforce_useful_formula_fields.pdf

Thank You
