Answer:
How to write smallest OR first 6 digit number:
let the 6 digit no= A B C D E F
Now at A we can not take 0,else 012345=12345
is a 5 digit number only
So for minimum 6 digit no A=1
B,C,D E anf F can have 0
so B=C=D=E=F=0
So smallest 6 digit No= 100000
let the 6 digit no= **A B C D E F**
the biggest digit is 9 so A=B=C=D=E=F=9
So biggest 6 digit No=999999
Now we take example :
from 5 to 10 numbers
are 5,6,7,8,9,10 ( 6numbers)
Or 6=(10–5)+1=5+1=6
THus we can say thetotal numbers from A to B are
N=(B-A)+1………………………..(1)
Thus total numbers from 100000 to 999999
Putting A=100000 and B= 99999 in(1)
N=(999999–100000)+1
=1000000–100000
=Smallest 7 digit No- Smallest 6 digit no
N=9,00,000
=9*100000
N=9*smallest 5 digit number
Thus we can write
Sum of n digit numbers=9*(smallest n-1 digit number)
N=9*10^(n-1)
