Direction: In these questions, two equations numbered I and II are given. You have to solve both the equations and mark the appropriate option. Give answer

I.\[5{{x}^{2}}-38x-21=0\]

II.\[2{{y}^{2}}-15y+28=0\]

A)  if\[x>y\]                      

B)  if\[x\ge y\]        

C)         if\[x<y\]          

D)         if\[x\le y\]

E)  if \[x=y\] or relationship between \[x\] and \[y\] can't be established.

Correct Answer: E

Solution :

Step II.\[-\frac{8}{2}\]             \[-\frac{7}{2}\]

Step III.\[y=\pm 4,\,\,+\frac{7}{2}\]

Hence no relationship can be established.
