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

(i) if\[x>y\]

(ii) if\[x\le y\]

(iii) if \[x<y\]

(iv) if\[x\ge y\]

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

I. \[5{{x}^{2}}-9x-18=0\]

II. \[2{{y}^{2}}-3y-9=0\]

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.\[-\frac{15}{5}\]              \[+\frac{6}{5}\] Step III. x = 3, \[-\frac{6}{5}\] Step II.  \[-\frac{6}{2}\]              \[+\frac{3}{2}\] Hence relationship can?t be established
