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. \[2{{x}^{2}}-15x+22=0\]              II.\[4{{y}^{2}}+19y+21=0\]

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: A

Solution :

Step II. \[-\frac{11}{2}\]             \[-\frac{4}{2}\] Step III. \[x=+\frac{11}{2},2\] Step II. \[+\frac{12}{4}\]            \[+\frac{7}{4}\] Step III. \[y=-3,-\frac{7}{4}\] Hence \[x>y\]
