Rep Power: 1 mantra rasi is on a distinguished road
Re: Number of zeros!!!!!!!!!!!!!!!!!

hey
i will give another simple technique.............
for first hundred natural numbers,
5 / 100
---------
5 / 20
----------
4
then answer is (20 +4)

lets take another example
for first 54 natural numbers
5 / 54
-------------
5 / 10
-------------
2
then now the answer is (10 +2) which is 12......
here we have to forget the remainder when divided by 5........just place the quotient........
i.e forget 4 by dividing 54 with 5.....
then it is easy for any number of natural numbers starting from 1.....
