wrong answer (Question: 99897.2 )

ans should be y>=x

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

I. 6x2 +77x +121 = 0


II. y2 + 9y – 22 =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. 6x2 +77x +121 = 0

⇒ 6x2 + 66x + 11x + 121 = 0

⇒ 6x (x  + 11) + 11 (x + 11) = 0

⇒ (x + 11) (6x + 11) = 0

⇒ x = -11 or – \(\cfrac{11}{6}\)

II. y2 + 11y – 2y – 22 = 0

⇒ y (y + 11) -2 (y + 11) = 0

⇒ (y – 2) (y + 11) = 0

⇒ y = 2 or -11
