Quantitative Aptitude (SBI-CL) Quadratic Equations

In the following question two equations are given in variables X and Y. You have to solve these equations and determine the relation between X and Y.

X³ = 64

2y² - 17y + 36 = 0

X ≤ Y

X < Y

X ≥ Y

X > Y

X=Y or No relation can be established

X³ = 64
X= + 4
2y2 - 17y + 36 = 0
2y2 - 8y - 9y + 36 = 0
2y(y - 4) - 9(y - 4) = 0
(2y - 9)(y - 4) = 0
Y= 4, 9/2
X ≤ Y
