Statement 1: \(3x=4y => \frac{x}{y}=\frac{4}{3}\)

if \(x\) and \(y\) are positive then \(x>y\) but if \(x\) & \(y\) are negative then \(x<y\). Insufficient

Statement 2: as \(k>0\) so both \(x\) & \(y\) are positive. Divide \(x\) by \(y\) to get \(\frac{x}{y}=\frac{4}{3}>1=>x>y\). Sufficient

Option \(B\)
