Hello,
Do you already know the correct answer? If so, please share it here.

this answer is correct

I think this is the right decision

possible last 2 digits(divisibility rule for four):

00

04

08

12

16

20

24

28

32

36

40

44

48

52

56

60

64

68

72

76

80

84

88

92

96

25 possibilities. Out of these, the ones ending with 0 don't work. (Can you see why?)

So, 00, 20, 40, 60, and 80 don't work. 

20 possibilities.

How did you decide that? By what formula?
