IMO A
I X is an even integer.
-4-2+0+2+4 = 0
-2+0+2+4+6=10
32+34+36+38=140
The sum of 5 consecutive even integers is always an even integer (and a multiple of 10).
Hence x is always an even integer.
II X is a non zero integer.
-4-2+0+2+4 = 0
0/5= 0
Hence this statement is false.
III X is a multiple of 5
-2+0+2+4+6 = 10
X=10/5=2
2 is not a multiple of 5
Hence this statement is false
Answer is A
