Sorry to mentioned here that the artical published here... How to double your money is absoulately wrong. The calculation made here is wrong n making fool to others. For example... by investing 5000/- @ 8% p.a. and then adding another Rs 1000 at the end of 1st year , adding another Rs 2000 at the end of 2nd year and in last adding another Rs 3000/- at the end of 3rd year How it can make money double in 3 years time.
We actually invested 5000+1000+2000+3000 = 11000 /- and we are getting Rs 13000 + money out of which our money is Rs 11000/- and the balance is interest earned on this amount. So how can my money double when invested at the time of 1st year.
I really can't understand this.
However saving is a good habit and every one has to save something always for better future.
