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. \[7{{x}^{2}}-25x+22=0\]

II. \[{{y}^{2}}-6y+9=0\]

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: C

Solution :

Step II.\[-\frac{14}{7}\]              \[-\frac{11}{7}\] Step III. \[x=2,\frac{11}{7}\] Step II.  \[-\frac{3}{1}\]              \[-\frac{3}{1}\] Step III. \[y=3\] Hence \[x<y\]
