Direction: In the following questions two equations numbered I and II have been given. Solve both the equations and give answer.

I. \[8{{x}^{2}}+22x+15=0\]     II. \[14{{y}^{2}}-17y+5=0\]

A)  \[x<y\]

B)  \[x>y\]

C)  \[x=y\] or no relation can be established

D)  \[x<y\]

E)  \[x>y\]

Correct Answer: D

Solution :

  Step II. \[\frac{12}{8}\frac{10}{8}\] Step III. \[x=-\frac{3}{2},-\frac{5}{4}\] Step II. \[-\frac{10}{14}-\frac{7}{14}\] Step III. \[y=\frac{5}{7},\frac{1}{2}\] Hence \[x<y\]
