Write a ten digit no in such way that like 2nd digit will represent no of 2‟s in a number, 0th digit will represent no of 0‟s in a number, 9th digit will represent no of 9‟s in a number, and so on.

• 6210001000 ll satisfy the condition
  
  0th digit is 6--> no. of 0's is 6
  1st digit is 2--> no. of 1's is 2
  2nd digit is 1--> no. of 2's is 1
  6th digit is 1--> no. of 6's is 1

• first start with 0000000009
  0000000018
  2000001007
  2100001007
  2100010006
  
  so ans is 2100010006

• 6210001000 ,
  6-> represnts "six" no. of zeros.
  2-> represnts "two" no. of ones.
  1-> represnts "one" no. of twos.
  6+1+1+2=10

• The answer may be any 10-digit no. where sum of its digits is 10.
  
  If you are asking about the number of such digits, some P&C concepts would need to be applied in here.

• I think they given the question wrong they must have specify the zero th position in the left or right.
  if we take the right as zeroth then it is impossible because to have a valid 10 digit number 9th must be at least 1 . hence there will be one 9 in the digit . if there is a 9 then there should be some digit 9 times but then it is not remain 10 digit number. so the 0th digit mus be from left

• 0000000009 -> 0th digit representing no of zeros in the no. & so on

• 0001000126 ->six 0's, two 1's, one 2,zero 3, zero 4, zero 5, one 6, zero 7, zero 8, zero 9

• considering 0th digit in d left -> 8000000001

• it's so simple
  answer should be:
  0000000009
  where 0th digit is from left to right.
  here 0th digit is 9 because no of o's is 9.
  and other is 0 because their numbers is 0.

  no of 0's--8
  no of 1's--1
  no of 2's--0
  so on
