If 1/3 < z <2/3 , then what is the value of z?

(1) When positive integer x is divided by 2, the result is z --> \(z=\frac{x}{2}\) --> \(\frac{1}{3}<\frac{x}{2}<\frac{2}{3}\) --> \(\frac{2}{3}<x<\frac{4}{3}\) --> since \(x\) is an integer then \(x=1\) (the only integer in that range) --> \(z=\frac{x}{2}=\frac{1}{2}\). Sufficient.

(2) When positive even integer y is divided by 12, the result is z --> \(z=\frac{y}{12}\) --> \(\frac{1}{3}<\frac{y}{12}<\frac{2}{3}\) --> \(4<y<8\) --> since \(y\) is an even integer then \(y=6\) (the only even integer in that range) --> \(z=\frac{y}{12}=\frac{1}{2}\). Sufficient.

Answer: D.
