The sum of three consecutive odd numbers is always divisible by:
I. 2 II. 3 III. 5 IV. 6
Pick:
A) Only I  B) Only II  C) Only I and II  D) Only II and IV  E) None of these
Let the three consecutive odd numbers be (2x+1), (2x+3) and (2x+5). Their sum = (6x=9)= 3 (2x+3), which is always divisible by 3.   Answer: Only II
