Thanks for the very good advice in real practical terms with proper logic and mathmatical formuls, also would like to say that as on date people thinks there is no interest in the banks in fixed deposit but u emphasis on the fix deposit which safe way to save money. The advice is help full at all time if ot applicable peoples like me who is turning arround 40 will help to the childrens who are growing up and suppose to start earning very soon in near future. The most important thing which learnt is " earning, saving,investing" all are diffrent saving is an art, investing needs smartness and earning is common to all even a rickshaw puller also earning.
