Folks I was just going thru the PP notes and found that 0 is part of the even set. I couldnt understand why... I am still to check my school books but how can zero be even or odd. 0 isnt divisible by 2 . So whats the logic ?

Even - 2n
Odd 2n + 1
Therefore by definition 0 is odd.

Could someone explain to me why should we consider 0 as a multiple of 5? I came across such DS question in the KAPLAN book

Following this logic, 0 is a multiple of any number, not 5 only. So, many questions are possible here. A basic definition of a multiple is:

N is multiple of 5 if N=5k in which k is an integer. So, 0 seems legal. But usually the actual GMAT avoids this kind of ambiguities.
