Root of quadratic equation $$(ax^{2} + bx + c =0)$$ = $$\frac{-b \pm \sqrt{b^2 -4ac}}{2a}$$
For equation I : a=9 , b = -37 and c= 30
On solving the quadratic equation I we get x = (3) or (20/18)
For equation II : a=3 , b = -19 and c= 30
On solving the quadratic equation I we get y = (3) or (20/6)
It is clear that y>x
Option A is correct answer.
