Total number of 4 digit number do not having 3 or 6.

• so there are four places for digits i.e _ _ _ _
  for the first place, there are 7c1 possible values (i.e. 1,2,4,5,7,8,9) = 7
  for second place , there are 8c1 values (0,1,2,4,5,7,8,9) so = 8
  for third place , there are 8c1 values (0,1,2,4,5,7,8,9) so = 8
  for fourth place , there are 8c1 values (0,1,2,4,5,7,8,9) so = 8
  so total numbers are
  7 * 8 * 8 * 8 = 3584 no.
