If the sum of 10 consecutive integers is x, which of the must be true?
I. x is even
II. x is odd
III. x is a multiple of 3	Select the correct option:
A) I only  B) II only  C) III only  D) I and III  E) II and III
sum of 3 consecutive integers   = (n) + (n+1) + (n+2) ++ (n+3) + (n+4) + (n+5)+(n+6)+(n+7)+(n+8)+(n+9)   =10n+45   = even + odd = odd   = 5(2n+9) = divisible by 5   Hence, x is even and divisible by 5.   Answer: I and III
