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

I.\[7{{x}^{2}}+29x+24=0\]        II. \[5{{y}^{2}}+22y+4=0\]

A)  if \[x>y\]                    

B)  if \[x<y\]        

C)       if\[x<y\]         

D)       if \[x>y\]        

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

Correct Answer: E

Solution :

Step II. \[+\frac{21}{7}\]            \[+\frac{8}{7}\] Step III. \[x=-3,-\frac{8}{7}\] Step II. \[+\frac{10}{5}\]            \[+\frac{12}{5}\] Step III. \[y=-2,-\frac{12}{5}\] Hence relationship can't be established.
