Question: Is \(\frac{xy}{z} > 0\)
Put otherwise, we want to determine whether xy & z have the same sign ?
Statement 1
\(xyz > 0\)
\((xy)z > 0\)
xy and z are both positive or both negative. Hence the sign is same. Sufficient.
Statement 2
\(yz > 0\)
We don't know the sign of x, hence the statement is not sufficient.
