\(\frac{x}{4}\)=integer?

(1) x + 2 is divisible by 2

\(\frac{x+2}{2}\)=integer =>x=2, 4, 6, 8....(all multiples of 2)

If x=2, is \(\frac{2}{4}\)=integer? NO

If x=4, is \(\frac{4}{4}\)=integer? YES

If x=6, is \(\frac{6}{4}\)=integer? NO

INSUFFICIENT!

(2) 6 is a factor of 3x

\(\frac{3x}{6}\)= integer => \(\frac{x}{2}\) = integer =>x=2, 4, 6, 8....(all multiples of 2)

If x=2, is \(\frac{2}{4}\)=integer? NO

If x=4, is \(\frac{4}{4}\)=integer? YES

If x=6, is \(\frac{6}{4}\)=integer? NO

INSUFFICIENT!

(1) + (2)

\(\frac{x+2}{2}\)=integer and \(\frac{x}{2}\) = integer.........Same as individual statements...no extra information
INSUFFICIENT!

Hence, answer is option E.

P.S: Please check the OA since it says the answer is option C

Bunuel please help confirm the OA
