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.\[2{{x}^{2}}-13x+20=0\]

II.\[2{{y}^{2}}-8y+8=0\]

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: A

Solution :

I. Step II.\[-\frac{8}{2}\]             \[-\frac{5}{2}\] Step III.\[x=+4,\,\,+\frac{5}{2}\] II. Step II.\[-\frac{4}{2}\]             \[-\frac{4}{2}\] Step III.\[y=+2,\,\,+2\] Hence, \[x>y\]
