heres a weird one part d any help pls?

but if a number ends in 0 it is also divisible by 5 right??? so the answer should be 672???

ik that the last digit must be 0 or 5, leaving us with the ss now being 8 values. so p(div by 5) = 8*7*6*1 (if its 0) and the same for 5 (=336+ they both give 336, so wouldn't you just multiply 336 by 2 together to get the answer????

part d help anyone?
