wrong option (Question: 100166.3 )

when x=+11 y1=+11

x=+11 y2=-11

In one case x=y and in second case x>y so option should be x>=y

Question:
DIRECTIONS: In the given question two equations numbered I and II are given. You have to solve both the equations and give answer if:

I. x – \(\sqrt{121}\) = 0


II. y2– 121 = 0

Options:
A) x > y
B) x ≥ y
C) x < y
D) x ≤ y
E) x = y or the relationship cannot be established
Solution:

I. x = \(\sqrt{121}\) = +11

II. y2 = 121

∴ y = ±\(\sqrt{121}\) = ± 11
