  According to me total 20 ways.

• 30..
  pairs with zero at last three are 12 so 2*1*12=24
  and not zero at last three are 6 so 1*1*6=6
  so total 30

• 36
  2X18(triad of no divisible by 8) = 36

• the combination is which of 5 digit which divisible of 8 is:
  last three digit:- 024,048,064,240,208,264,280,248,408,480,608,624,648,680,640,824,840,864
  so total :- 18 ways.

• assuming repetition is allowed
  1st place can be 4 numbers except 0
  2nd place can be all 5 numbers
  now digits including 3rd,4th,5th must be divisible by 8 so
  these will be
  000
  008
  024
  048
  064
  080 like wise for 2, 4, 6, 8 all numbers will be 6*5(repetition allowed)=30
  so total numbers are= 4*5*30=600

• assuming repetition is allowed
  1st place can be 4 numbers except 0
  2nd place can be all 5 numbers
  now digits including 3rd,4th,5th must be divisible by 8 so(last three digit should be divisible by 8)
  these will be
  000
  024
  040
  048
  064
  080
  088
  and same way for 2,4,6,8
  so total is 8*5=40
  answer is 4*5*40=800 ways

• Arrange at unit place 0 2 4 6 8 respectively.
  Then arrange other digits .each unit digit will make total 12 arrangements.
  Check division by 8. U will get total 18 arrangements
