How many times the digit zero would appear
in the sequence of whole numbers upto (and
including) 100 ?
(A) 10 (B) 9
(C) 11 (D) 12

• 12 times
  one zero digits are 10,20,30,40,50,60,70,80,90=9 zeros
  100=2 zeros
  since given sequence is of whoe numbers so it starts from 0
  hence tota no. of zeros are 9+2+1=12
