Instructions
In the following questions two equations numbered I and II are given. You have to solve both the equations and
Give Answer If
a: x > y
b: x ≥ y
c: x < y
d: x ≤ y
e: x = y or the relationship can not be established
Solution
I : $$x^{2} - 463 = 321$$
=> $$x^2 = 321 + 463 = 784$$
=> $$x = \sqrt{784} = \pm 28$$
II : $$y^{2} - 421 = 308$$
=> $$y^2 = 308 + 421 = 729$$
=> $$y = \sqrt{729} = \pm 27$$
$$\therefore$$ No relation can be established.
