GMAT Quantitative Reasoning Practice Test 3

Let's go over each statesman's at a time.
1 , the multiplication of two consecutive numbers is always an even number.
2 , Try $\mathit{x}=2,\mathit{y}=3$
In this case $\frac{3}{2}$ is bigger than 1 but if you choose $\mathit{x}=-3,\mathit{y}=-2,\mathit{y}/\mathit{x}$ is $2/3$ and that's smaller than 1 . Therefore, this statement is not always true.
3 , the sum of two consecutive numbers is always odd, try some numbers. Therefore, only statement 2 is false.
