If x is an even integer and y = 5x + 1, which of the following CANNOT be a divisor of y?
Select the correct option: A) 11 B) 31 C) 21 D) 41 E) 30
x takes even values as 2,4,6,8.,   y=5x+1   x is an even term so 5x must be an even term when it adds with 1 so it must be a odd integer   30 didn't follows this condition ans is 30
