The sum of all the numbers formed by taking all the digits from 3,4,5,6,7 is:

The sum of all the numbers formed by taking all the digits from 3,4,5,6,7 is:

The sum of all the numbers formed by taking all the digits from 2,3,4,5 is:

The number of numbers having 3 in the unit place= 3! =6

The number of numbers having 4 in the unit place= 3! =6

The number of numbers having 5 in the unit place= 3! =6

So the sum of the digits in the unit place of all the numbers=

=12+18+24+30

=84

Similarly the sum of the digits of all the numbers in each of the other places=84

The required sum =

=84(1000+100+10+1)

=84

=93324
