Best possible investment to save as much taxes?I am a 28 year male with a CTC of 12.5 lakhs and I was hopi?

I am a 28 year male with a CTC of 12.5 lakhs and I was hoping you can help me with use of a case study on what the best investments could I make to save maximum taxes based on the latest budget recommendations. I already have a housing loan with an exemption of 1.5 lakh. Besides this I have no other investments to save taxes..I have no children and dependants as well..I was hoping in having a mix of Public PF, Postal savings, some insurance covers, medical insurance etc which would help me in saving the maximum taxes for the upcoming financial year. My whole agenda is to invest amounts that I would otherwise pay as taxes rather than investing anything from my pocket :) I would appreciate if anyone could give me actual breakup of the amounts I need to invest to save taxes. Thanks in Advance..
