Given xy \(\neq\) 0
=> x \(\neq\) 0 and y \(\neq\) 0
Statement 1
y < 0
=> \(\frac{1}{y}\) < 0
We know for any value of x, |x| \(\geq\) x
=> If we multiply above equation with \(\frac{1}{y}\) which is < 0, the inequality sign reverses
=> \(\frac{|x|}{y} \leq \frac{x}{y}\)
Hence statement 1 is sufficient to say \(\frac{|x|}{y}\) is not greater than \(\frac{x}{y}\)
Statement 2
x = y
=> \(\frac{x}{y}\) = 1
=> \(\frac{x}{y}\) is always positive
=> \(\frac{|x|}{y}\) is either positive with a maximum value of \(\frac{x}{y}\) or negative based on sign of y
In both the cases \(\frac{|x|}{y} \leq \frac{x}{y}\)
Statement 2 is sufficient
Hence statement s is sufficient to say \(\frac{|x|}{y}\) is not greater than \(\frac{x}{y}\)
Hence option D
=> x \(\neq\) 0 and y \(\neq\) 0
Statement 1
y < 0
=> \(\frac{1}{y}\) < 0
We know for any value of x, |x| \(\geq\) x
=> If we multiply above equation with \(\frac{1}{y}\) which is < 0, the inequality sign reverses
=> \(\frac{|x|}{y} \leq \frac{x}{y}\)
Hence statement 1 is sufficient to say \(\frac{|x|}{y}\) is not greater than \(\frac{x}{y}\)
Statement 2
x = y
=> \(\frac{x}{y}\) = 1
=> \(\frac{x}{y}\) is always positive
=> \(\frac{|x|}{y}\) is either positive with a maximum value of \(\frac{x}{y}\) or negative based on sign of y
In both the cases \(\frac{|x|}{y} \leq \frac{x}{y}\)
Statement 2 is sufficient
Hence statement s is sufficient to say \(\frac{|x|}{y}\) is not greater than \(\frac{x}{y}\)
Hence option D

I think it should be D.
Statement 1: y<0
x>0 or x<0
If x>0
\(\frac{|+x|}{-y} = \frac{+x}{-y}\)
If x<0
\(\frac{|-x|}{-y} < \frac{-x}{-y}\)
Sufficient.
\(\frac{|x|}{y} ≤ \frac{x}{y}\)
Statement 2: x=y
If x and y are less than 0
\(\frac{|-x|}{-y} < \frac{-x}{-y}\)
If x and y are greater than 0
\(\frac{|+x|}{+y} = \frac{+x}{+y}\)
Sufficient.
\(\frac{|x|}{y} ≤ \frac{x}{y}\)
Statement 1: y<0
x>0 or x<0
If x>0
\(\frac{|+x|}{-y} = \frac{+x}{-y}\)
If x<0
\(\frac{|-x|}{-y} < \frac{-x}{-y}\)
Sufficient.
\(\frac{|x|}{y} ≤ \frac{x}{y}\)
Statement 2: x=y
If x and y are less than 0
\(\frac{|-x|}{-y} < \frac{-x}{-y}\)
If x and y are greater than 0
\(\frac{|+x|}{+y} = \frac{+x}{+y}\)
Sufficient.
\(\frac{|x|}{y} ≤ \frac{x}{y}\)
