• The is wrong:
  correct question is : The minimum number of digits required to form every number which is greater than 900 and less than 9,000 is:
  Solution :
  We have to find the minimum number of numbers required to form every number from 900 to 9,000.
  Unit place of a number from 900 to 9,000 can be formed using 0 to 9 digits. i.e., 10 digits.
  10's place of a number from 900 to 9,000 can be formed using 0 to 9 digits. i.e., 10 digits.
  100's place of a number from 900 to 9,000 can be formed using 0 to 9 digits. i.e., 10 digits.
  1000's place of a number from 900 to 9,000 can be formed using 1 to 9 digits. i.e., 9 digits.
  
  Therefore, total number of numbers required is 10 + 10 + 10 + 9 = 39.

• it might be from 900 to 9000.if that so then the answer is 39
  units place possible numbers from 900 to 9000 is 0 to 9 that is 10 numbers
  10 s place possible numbers from 900 to 9000 is 0 to 9 that is 10 numbers
  100 s place possible numbers from 900 to 9000 is 0 to 9 that is 10 numbers
  10000 s place possible numbers from 900 to 9000 is 0 to 9 that is 9 numbers except 0
  so finally the answer is 10+10+10+9=39
