Rule of 72, Rule of 70 & Rule of 69 are a few vedic mathematics techniques used to find out approximately when investment doubles at a given rate of interest.
The Rule of 72/70/69 are applied in the following manner:-
Numerator is always 72/70/69
Denominator is the rate of interest p.a.
But many of the financial wizards find the Rule of 72 most convenient as it can be divided by a number of small numerals like 2,3,4,6,8 & 9
For Example:-
You have a Principle of Rs.10,000.
Rate of Interest = 9% per annum
by applying rule of 72 we get 72/9 = 8 years
Actually it doubles at 8.043 years
so very close.
