Direction: In this question 2 equations numbered I and II are given. You have to solve both the equations and find out the correct option.

  1. Ⅰ. 24x2 + 38x + 15 = 0
    Ⅱ.12y2 + 28y + 15 = 0
    1. x ≤ y
    2. x > y
    3. x ≥ y
    4. x < y
    5. x = y, or Relationship between x and y cannot be established
Correct Option: C

According to question ,we can say that
From equation Ⅰ. 24x2 + 38x + 15 = 0
⇒ 24x2 + 20x + 18x + 15 = 0
⇒ 4x(6x + 5) + 3(6x + 5) = 0
⇒ (4x + 3)(6x + 5) = 0

∴ x = -

From equation Ⅱ.12y2 + 28y + 15 = 0
⇒ 12y2 + 18y + 10y + 15 = 0
⇒ 6y(2y + 3) + 5(2y + 3) = 0
⇒ (6y + 5)(2y + 3) = 0
∴ y = -
