Find the number of 6 digit numbers consisting only of even digits

• even digits are 0,2,4,6,8... as we normally consider 0 as even number.
  number of 6 digit numbers consisting only of even digits= 4*5*5*5*5*5 = 4*3125 = 12500 as first digit can not be zero.

• since it is already said it is a 6 digit number so the first digit can never be 0. moreover it is also said that all the digits are made by even digits. so digits used are 0,2,4,6,8.
  now as 0 can't be used in the first place the first place can be filled by 4 ways. and the rest 5 places can be filled by 5 ways.(repeatations are allowed)
  so the answer is 4*5^5.

• even digits are 0,2,4,6,8 so
  possibility for 0 =4
  for 2=5
  for 4=5
  for 6=5
  for 8=5
  so final answer would be 4*5*5*5*5=2500

• there are 5 even digits i.e 0, 2, 4, 6, 8 and 6 places, so the answer will be 4*5C4=20
