Question:
Directions : In the following questions two equations numbered I and II are given. You have to solve both the equations and Give Answer If


I. x2 - 10x + 24 = 0

II. y2 – 9y + 20 = 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. x2 - 10x + 24 = 0

⇒ x2 – 6x – 4x + 24 = 0

⇒ x (x – 6) - 4 (x – 6) = 0

⇒ (x - 4) (x - 6) = 0

∴ x = 4 or 6

II. y2 – 9y + 20 = 0

⇒ y2 – 5y – 4y + 20 = 0

⇒ y(y – 5) - 4(y – 5) = 0

⇒ (y – 4) (y – 5) = 0

∴ y = 4 or 5

∴ no relation exist
